battery pack without removing it from the radio or to recharge the
battery pack separately. The charger is able to recharge both Li-Ion
and Ni-MH battery pack.
2At the end of the recharge operation, it is possible to leave the
radio/battery pack in the charger, because the latter has a special
protection that prevents the battery pack from being damaged by
overvoltages.
2Battery packs tend to loose their charge if they are not used
(automatic discharge). This condition is perfectly normal. All
models of battery packs tend to loose 10 - 20% of their power
after a few days.
IIf the battery pack is new, it is necessary to fully recharge
it before using it. Then, it is sufcient to follow the
recommendations given in paragraph 4.4.a.
IAlways use the battery-charger with the above-described

5 Basic features
5.1 Switching the device on and off
Turn the On/Volume knob clockwise until it clicks: the LCD displays
switchesonandthedeviceissuesaconrmationbeep.
2The backlighting of the LCD display switches off automatically
after ve seconds for energy saving purposes, while the display
remains on.
To switch the transceiver off, turn the On/Volume counterclockwise.
5.2 Backlighting
When you switch the device on or press one of the HI/LO, SCAN/
LOCK, MENU or MON keys, the device automatically enables the
backlighting for approximately ve seconds to allow you to read
the displayed messages if the lighting is not adequate. To keep the
backlighting on for 5 seconds more, press another key.
2The backlighting of the display consumes battery energy and
should therefore be used sparingly.
5.3 Checking the level of the batteries charge
When the transceiver is in standby mode, the battery charge indicator
continuously displays the residual charge of the battery.
2Icon indicates that the charge is insufcient and that the
device will soon switch off.
2The consumption of the battery charge is affected by the volume
level set.
5.4 Adjusting the squelch (suppressing background noise)
The radio is tted with a device called squelch that attenuates
the background noise when no signals are present. The enabling
thresholdcanbeadjustedaccordingtoyourspecicneeds.
1) Briey press MON twice. Sq displays, while the right section
displays a number from 1to 8, depending on the squelch level
you have set.
2) Press qseveral times to set the enabling threshold on 1(minimum
value). You will hear a slight background noise.
3) If the radio is not receving signals, press pseveral times to
gradually increase the squelch value and stop as soon as
you detect the minimum value that guarantees a stable noise
suppression.
4) Press PTT (or wait ve seconds). The device returns to the
standby mode and stores the settings you have selected.
2Make sure you do not set an excessively high squelch level
because in this case you may not be able to receive weaker
signals. On the other hand an excessively low squelch value
could enable the squelch even when no signals are present.
2This adjustment must be carried out within ve seconds, otherwise
the device returns to standby mode and stores the currently set
value.
ISquelch must always be adjusted when no signals are
present.
5.5 Selecting the operating channel
1) Press MENUonce.Thedisplayashes.
2) Press por qto select the desired channel. To quickly scroll the

10
English
channels hold down por q.
3) Press PTT(orwaitveseconds)tostorethesetting.
2It is obvious that other parties shall also have to select the same
channel, otherwise communications will not be possible.
2This adjustment must be carried out within ve seconds, otherwise
the radio returns to the standby mode storing the currently set
channel.
5.5.a How to select the channel
The HP450 2A radio has been programmed as follows:
• Channelsfrom1to 8are programmed with the 8 radio frequencies
of the PMR446 band
• Channels from 9 onwards are programmed with the same
repeated radio frequencies (for example channel 9has the same
frequency of channel 1, channel 10 has the same frequency of
channel 2, etc.), but also include CTCSS tones or DCS codes. If
you select these channels, CTC or DCS displays.
2For the PMR band, your dealer will inform you about the channels
to use
IIf you need to communicate with transceivers of different
brands, it is generally preferable to use one of the rst eight
channels to ensure maximum compatibility. It is obviously
necessary to select the less used channel of your area. If the
parties you are communicating with use a HP450 2A device
(or a device with CTCSS tones), you may choose any channel.
If all the eight PMR446 frequencies are occupied in your area,
you can select a channel from 9 to 16 (the less busy one) to
allow the CTCSS tone or DCS code to enable you to listen to
communications of the members of your group only.
2For more information on CTCSS tones and DCS codes, see O5.8
and 5.9.
5.6 Receiving and transmitting
2The reception/transmission mode described below is the so-called
"open trafc mode", which is simplest one. It is however possible
also to set other modes as described in paragraph 5.8.
During reception and transmission try and keep the aerial as vertical
as possible so that the signal can be transmitted without hindrances.
This precaution optimises the radio signal.
5.6.a Reception
As soon as the signal has been received, the squelch disables
automatically, the status LED turns green and icon displays
showing the intensity of the received signal.
2If the signal is received fragmented because of weak signals, try
using the monitoring feature.
5.6.b Transmission
1) Verify that other parties are not connected to the selected channel
(status LED off).
2) Hold PTT down: the status LED turns permanently red to indicate
that the transmission is in progress, while indicator indicates
the transmission power.
3) Waitafewseconds,thentalknormallyataboutvecentimetresfrom
the transceiver transmitter. Your message will be simultaneously
heard by all the parties listening to the same channel.
4) To end the communication, press PTT: the status LED switches
off to indicate that the device has returned to the reception mode

11
English
and icon disappears.
2Only one user at a time can talk during radio communications.
Therefore, it is important not to transmit when you are receiving a
communication and use the transmission mode sparingly to allow
other users to use the feature.
2Transmission consumes a signicant amount of energy and
should therefore be used sparingly to prolong the battery life.
Alternatively, it is also possible to select a low transmission
power.
2If you are unable to contact a station that you have no problems in
receiving, the station may be using CTCSS tones or DCS codes
(O5.8).
5.7 Busy channel lockout
The BCLO and TOT functions are disabled by default.
If BCLO has been enabled and the channel is busy, the selection of
PTT or CALL will have no effect and the radio will issue an error beep.
As soon as the channel is free, PTT and CALL shall automatically
resume ordinary operation.
5.7.a Transmission timer (TOT)
The HP450 2A radio can be programmed with a transmission timer
that temporarily blocks transmission if the radio has been used
beyond the maximum time permitted.
The radio is forced in reception mode if it continues transmitting
after the preset timer threshold has been reached. To restart the
transmission, it is sufcient to release and then press again the
PTT.
5.8 Operating modes (open or restricted traffic)
HP450 2A can be used in two modes:
Mode name: Default
setting
Comments
Opentrafc
(without CTCSS/
DCS)
From channel
1 to 8
Guarantees maximum
compatibility with the devices of
other manufacturers. However, if
the channel you are using is used
also by other parties, you will also
receive their communications.
Restrictedtrafc
(with CTCSS/
DCS)
From channel 9
onwards (with
several CTCSS
tones or DCS
codes)
CTCSS and DCS tones are
similar to access codes and
enable the radio to communicate
only with the parties that use the
same frequency or have set the
same code.
2For information on how to change the CTCSS tone or DCS code
of a channel programmed in restricted trafc mode, see O5.9.
2The restricted trafc mode enables several radios to use the same
radio frequency. However, if several parties (for example a user
of group A and a user of group B) simultaneously use the same
channel for transmission purposes, interference may occur. For
this reason, it is advisable not to transmit if the radio signals that
the channel is busy although there are no communications.
2The restricted trafc mode does not guarantee the privacy of
communications. In this mode it in fact possible to listen also
to parties that use CTCSS tones/DCS codes, although it is not
possible to call them because they would not be able to receive the

12
English
call. To communicate in condential mode, enable the scrambler
O6.5.
2If you need to use the HP450 2A radio next to electric equipment
that generates impulses that frequently enable the squelch of
the radio (that is the radio cannot be permanently silenced when
there are signals and noise can be occasionally perceived), it is
generally preferable to use the restricted trafc mode.
5.9 Programming the CTCSS/DCS codes
It is possible to change the CTCSS tones or DCS codes on all the
channels. You can set different codes in TX and RX.
5.9.a Selecting the CTCSS tones
1) Select the operating channel.
2) Press MENU twice. CTC displays on the left along with the

• Orange: indicates the receipt of a signal without a CTCSS/DCS
tone or with a different CTCSS/DCS tone (the volume will not be
enabled)
• Red: indicates that the transmission is in progress (as in the open
trafcmode)
5.10 Monitoring function - Monitor/squelch
This feature can be used to monitor the selected channel before
transmitting and receiving low intensity signals. Press MON to
disable the mode (CTCSS).
To disable the squelch (noise reduction), hold MON down for
approximately 3 seconds. In this mode, you can hear all the noise
present in the environment.
2The disabling of the squelch increases the consumption of the
battery power.
