channels hold down p or q.
3) Press PTT (or wait five seconds) to store the setting.
2 It is obvious that other parties shall also have to select the same
channel, otherwise communications will not be possible.
2 This adjustment must be carried out within five 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:
• Channels from 1 to 8 are 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 9 has 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.
2 For the PMR band, your dealer will inform you about the channels
to use
I If you need to communicate with transceivers of different
brands, it is generally preferable to use one of the first 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.
2 For more information on CTCSS tones and DCS codes, see O 5.8
and 5.9.
5.6 Receiving and transmitting
2 The reception/transmission mode described below is the so-called
"open traffic 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.
2
If 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) Wait a few seconds, then talk normally at about five centimetres from
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
