And now, let’s communicate!
SWITCHING THE RADIO ON/OFF
1. Rotate the VOL knob clockwise. The radio will run a rapid autotest at the
end of which an audible “tone” will indicate that the radio is operational.
2. The display will show the current operating mode.
3. The current operating mode will be saved automatically within 0.5
seconds of any change made by the user.
4. Note: The following icons will be displayed depending on the operating
mode.
• “Low” refers to output power/nothing stays for high.
•“•” indicates that the channel is in the scan list.
•“P” is displayed when the channel has priority in the scan list.
•“SAT” indicates that the channel has been programmed for CTCSS/DCS
•“”indicates battery level (blinking when the battery is low).
•“VOX” is displayed when the VOX facility has been selected.
•“”is displayed when the keypad is locked.Only the PTT button is
operational.
• To switch the radio off rotate the VOL knob counter-clockwise until a click
is heard.
ADJUSTING VOLUME
Turn the knob clockwise to increase the volume, counter-clockwise to reduce
the volume.
CHANNEL SELECTION
To select a channel:
• Press the key to increase the channel number or the key to
decrease the channel number.
CALLING ANOTHER PARTY
1. Check that the channel is not busy (status LED is not glowing). Do not
press the PTT button if someone else is speaking as both messages will
be lost.
2. Press the PTT button, the status LED will now glow red.
3. Hold the radio about 5-10cm away from your face and speak at a normal
volume across the front of the radio.
Keep the PTT button pressed for the duration of your speech.
4. Release the PTT button when you have finished speaking.
Note: Shouting into the microphone will not increase your range but will
cause an increase in distortion.
Note: Releasing the PTT button before you have finished speaking will result
in your message being lost.
CTCSS/DCS
Your ALAN HP 446 extrá can operate in two modalities:
• OPEN CHANNEL : all signals transmitted on the selected channel will be
heard. The status LED will glow green.
• GROUP MODALITY CTCSS/DCS: CTCSS and DCS tones are “access
tones” that allow you to receive only calls from parties using same chan-
nel and code.
The status LED will glow green when signals with the correct
CTCSS/DCS code are received, it will glow amber if signals with the
incorrect CTCSS/DCS code are received.

And now, let’s communicate! 7
English
Advantages with the Use of CTCSS/DCS
1. PRIVACY
Your ALAN HP 446 extrá with its 50 CTCSS tone sets and 104 DCS tones,
provides privacy between users co-existing on the same frequency
but using different CTCSS/DCS tones.
2. GROUP CALL
CTCSS and DCS may be used also to address “group call” to users with
the same CTCSS/DCS code.
However interference will be caused if more than one user transmits at
the same time, it is therefore recommended not to transmit if the status
LED is glowing (either green or amber).
HOW TO SET A CTCSS/DCS CODE
To set CTCSS/DCS codes:
Turn the radio off.
a. Press and hold the and buttons while turning the radio on.
b. Release the and buttons.
c. Press the or key to select the channel.
d. Press the function button, the display will now show the tone code.
e. Press the or button to select the code required.
Note: the number is shown in hexadecimal format, refer to
Appendix ∑for information on this numbering system.
f. Press the function button and switch the radio off to store the
setting.
PRESET CTCSS CODES
To facilitate CTCSS/DCS setting, your ALAN HP 446 extrá has been
programmed by the factory with a range of preset CTCSS codes (pls refer to
APPENDIX A ).
ENABLING/DISABLING CTCSS/DCS codes:
To enable pre-setted CTCSS/DCS press (MON) button once or twice until the
SAT icon appears on the LCD display. When the CTCSS/DS is enabled, the
speaker will be muted unless the correct CTCSS/DCS code is received.
MONITOR FUNCTION
The monitor function is used to check the activity on the selected channel
before transmitting.
The squelch (noise reduction device) is defeated by pressing and holding
the MON button for 3”. In this mode a continuous noise will be heard from
the loudspeaker.
Pressing once the MON button will result in defeating the SAT mode.
Note: Defeating the squelch and leaving the radio in this mode will result in
reducing battery life.
BUSY CH FUNCTION
Once programmed the BUSY CHANNEL LOCK OUT function, disables
transmission if the PTT button is pressed while the channel is busy.
TIME OUT TIMER
Your administrator/dealer may have programmed a “time out timer” to set the
maximum duration of conversation.
Timeout-timer, automatically switches the radio from transmit to receive if
your speech exceeds the pre-set time.
To defeat TOT simply release the PTT button and wait for a few seconds
before pressing the PTT button again (don't forget to check if the channel is
busy!).
TOT Helps extend your battery life!

Care and maintenance
BATTERY PACKS
Information on rechargeable batteries
• A correctly maintained battery pack will be good for at least 400
charge/discharge cycles.
• All batteries are prone to self-discharge while not being used, a nickel
metal hydride (NiMH) battery may lose up to 20% of the stored charge
within a few days.
Memory effect
The NiMH battery pack supplied with your ALAN HP 446 extrá are virtually
free of memory effect typical od the NI-CD elements. Although continuous
misuse, will eventually lead to a reduction in capacity.
Observing the following procedures will reduce memory effect and prolong
the life of the battery:
• Charge battery packs only when they are fully discharged, ie when
is blinking.
• Do not partially charge the battery.
• Cycle the battery at least once a month ( full discharge followed by a
charge).
• Having a spare battery means that you will always have a fully charged
battery and that both batteries will be in peak condition.
Erasing memory effect
Memory effect may be cured by applying 3-4 deep charge/discharge cycles:
a. Install the battery pack to be cycled on the radio, switch radio on and
leave until the radio switches off automatically, switch the radio off using
the VOL knob.
b. Wait for at least one hour and switch the radio on, leave until the radio
switches off automatically, switch the radio off using the VOL knob.
Repeat this at least three times.
c. Turn the radio off, insert into the base unit of the charger and charge the battery.
Istr. HP446 rev.1 - UK 20-07-2001 16:35 Pagina 9

English
10 Optional accessories
d. Check the life of the battery the next time it is used, repeat steps a. to c.
if memory effect is still present.
Note: If the problem persists then the battery pack is probably faulty, in
which case contact your dealer to arrange for purchase of a replacement
battery.
General Precautions
Please follow these precautions to avoid damage to the battery pack or the
transceiver.
• Do not short-circuit the battery terminals, this may cause a fire or an
explosion.
• Always un-plug the AC adaptor from the AC power source before
attempting to clean the charger or the radio.
• Do not store batteries to temperatures below -20°C or above +35°C
during normal use and do not charge batteries at temperatures below
+5°C or above +55°C.
RADIO MAINTENANCE
