Coverage
The maximum range is obtained during use in an open space.
The only limitations to the maximum possible range are environmental factors such as blockage caused by trees, buildings, or other obstructions. Inside a car or metallic constructions can reduce the range.
AND NOW, LET’S COMMUNICATE!
Open the battery compartment, hold the unit face down and unhook the battery holder in the lower part of the radio; gently slide the cover towards the bottom of the radio. Then, insert 3 x AA alkaline or rechargeable batteries, taking care to observe the correct polarity.
1 Switching your ALAN 466R on
Rotate the ON/OFFVOLUME [11] knob clockwise. The radio beeps 4 successive times with different tones (may be inhibited). The LCD [2] displays a “self-test” message for 1 second, it will then indicate channel 1 followed by 2 digits indicating the CTCSS tone stored (see paragraph “CTCSS Subaudio tones selection”).
2 Volume adjustment
To adjust the volume level, hold “MON" [8] key down for 1 second while rotating clockwise the ON-OFF/VOLUME [1] knob until you reach a comfortable listening level. Release the “MON’ [8] button.
Your Alan 45611 is now ready to receive and transmit.
3 Channel selection
Select the desired channel and relevant frequency by means of the [3] keys.
CHANNEL FREQUENCY (MHz)
01 446.00625
02 446.01 875

4 To transmit
For maximum speech clarity, hold the radio 4 to 10 cm away from your mouth, keep the PTT key [9] pressed and speak into the unit. During transmission the display [2] shows the icon
When you have finished talking, release the PTT [9]. The radio beeps to confirm to other users that your transmission has ended (Roger Beep). This function is enabled by default; to disable it, see paragraph 13 "Roger Beep”.
5 Reception
Simply release the PTT [9] key. The icon is displayed.
6 Background noise reduction / coverage extension (Autosquelch).
In your ALAN 456R the background noise reduction device (squelch) is activated by default. Hold MON [8] button down to deactivate it. In this way, even low level signals can be received.
ATTENTlON: MON [8] key disables also the CTCSS/DCS.
7 Auto power save
The ALAN 456R comes complete with an automatic current economy circuit. If the transceiver receives no
signal for 7 seconds or longer the “power save function” automatically activates. (SAVE blinks on the display). The battery life may increase by up to 50 %.
When the batteries are in need of charging, icon will be displayed [2]: it is necesasry to replace alkaline batteries or recharge the Ni-Cd/NiMH ones.
8 External charger jack [12].
We recommend use of the appropriate charger only.
Attention:never attempt to recharge alkaline batteries.
8.1 Metallic recharge contacts [13]:
They allow the battery recharge through the use of an optional desktop charger (model CA456 or CA456-2S).
9 Keypad lock
Hold MON key [8] down for longer than 3 seconds: the display will show the icon to confirm activation.
PTT [9], MON [8], CALL [10] and [6] keys will still be active.
Repeat the same procedure to unlock the keypad.
10 Hands-free tranamisalon mode (VOX) I Baby-sitter
The ALAN 456R has built-in VOX capability (automatic transmission). You can choose from 6 different VOX
sensitivity levels, depending on how noisy the environment is.
VOX activation
Set the PTT-VOX [7] switch to VOX position.
Speak into the microphone: hands-free transmission will start automatically.
Sensitivity setting
1 Turn the radio off by rotating the knob [1] anti-clockwise.
2 Press [6] key while turning the radio on; release the button and the display shows:
3 Push twice key; the display will show:
4 Select the desired sensitivity level by means of [3] controls.
Note:
01 is the highest sensitivity level (suitable with no background noise)
06 is the lowest sensitivity level (useful in very noisy areas).
Delay adjustment
This option keeps the radio in transmit mode after you stop talking. The delay can be adjusted (if it is set too short it may cause transmission to stop between some words) and allows you to speak at a steady rate with no lose of transmission.
5 Push once key; the display will show:
Follow the method described at step 4 and select the desired level such that the radio switches back to RX with the desired delay (01 = shortest delay; 06 = longest delay).
6 Press [6] key or turn the radio off to confirm settings.
To disable the VOX function, set the PTT-VOX switch [7] to PTT position.
11 Babysitter function
This feature is particularly useful to listen to a baby at a distance as you can automatically hear all sounds or noises close to the transmitter. This function needs two ALAN 456R. The Alan 456R used for the reception (RX) must have the PTT-VOX switch [7] set to “P11” and set on the same channel of the radio close to the baby (TX).
Babysitter function setting
1. Set the PTT-VOX switch [7] to “PTT”.
2. Turn the unit on while pressing [6] key.
3. Push key [5] until the display shows:
4. Using [3] controls, select one of the six sensitivity levels available (01= highest sensitivity - 06= lowest sensitivity); push [6] key: the display shows BA-BY
5. If the radio receives no sound after 1 minute roughly, BA-BY blinks on the display to confirm the babysitter function activation.
6. When your ALAN 456R receives a noise, if will send out a tone (heard from the radio in reception) and will switch into TX mode for about 10 seconds. It will then return to RX mode. This step will be repeated for three times.
7. When the radio no longer receives a noise, BA-BY will blink again.
The Babysitter function disables all the controls except for [6] key and [3].
The sensitivity level must be set according to the distance between the baby and the radio and to the background noise. (01 = highest sensitivity - 06= lowest sensitivity).
To deactivate the function, turn the unit off and on.
12 INTERCOM function
This is useful for motorcyclists as it allows DUPLEX conversation between the driver and passeng function; DUPLEX function simultaneous two-way communication, the same as a phone conversation.
For details of connecting the ALAN 456R and optional kit “MA4O”, see the instruction guide for this accessory. The conversation can be extended to other users operating on the same frequency. Transmission is possible with either manual PTT activation (PTT of the radio or of the accessory microphone) or by enabling the VOX. In the latter case, you have to shift the PTT-VOX switch [7] to VOX position and use an external microphone speaker/microphone.
13 ROGER BEEP: end transmission tone
When PTT [9] is released the radio will beep to confirm to other users that your transmission has finished.
To disable this function:
1. Turn the unit off.
2. Nold key [6] down while switching on the radio.
3. Press key [5] until the display shows:

18 CTCSS and DCS
Your Alan 456R can receive in two modes: open traffic and CTCSS/DCS.
Open traffic
You will hear any communication transmitted on the selected channel.
CTCSS/DCS
CTCSS and DCS tones are signalling systems that allow you to receive only messages coming from parties using the same channel and code. The speaker will remain muted until the correct CTCSS or DCS tone is received.
This mode allows you to share more radio networks on the same frequency. In this case you will receive only messages coming from parties sending the correct TX signalling.
CTCSS subaudio tones selection:
1) Switch the unit on.
2) Press [5] key until CTCSS appears on the display.
3) Select the desired tone using [3] controls (refer to the chart here below).
4) Push the key [6] for confirmation.
5) Now your ALAN 456R transmits and receives using the programmed CTCSS tone.
If you don’t want to select any CTCSS code, select “00”.
