L. S/RF Digital Meter
A digital 10-bar S/RF METER indicates the strength of the received signal (from S0 to S9+30) in the receive mode and
the transmitter RF output power (0 to 4W) in the transmit mode.
M. Alphanumeric Digit
This alphanumeric digit indicates the fifth and last figure (in KHz) of the operating frequency, when the full frequency
readout function is enabled.
N. LOW Icon
The LOW icon is lighted when the transmitter is in the LOW POWER (1W) mode.
O. LOCK Icon
The LOCK icon is lighted when the LOCK function has been enabled.
P. M1-M4 Icons
The M1-M4 icon is lighted when one of the four memory channels has been selected.
Q. Alphanumeric Digit
These four numeric or alphanumeric digits indicate :
- the first four figures of the operating frequency (in KHz), when the full frequency readout function has been
enabled
- the country code, in accordance with the programmed frequency band (i.e. DE, UK, CE, etc.)
- the operating channel number (01 to 80, according to the programmed frequency band), when the channel
number readout function is enabled
R. F Icon
The F icon is lighted when the F (Function) mode has been enabled, which allows the use of the dual function keys
(keys 6,7,8,9).
4. ESP Indicator
This LED indicator lights up in red colour when the ESP (Electronic Speech Processor) function is enabled. The ESP is an
RX & TX electronic modulation processor.
5. TX/RX Indicator
This green-red dual colour LED indicator lights up in green colour when radio is in receive mode and in red colour
when radio is in transmit mode.
6. AM/FM and M1 Key
This key allows to select the AM or FM operating mode in both RX and TX. The AM/FM operating mode selection is
possible only if it is allowed the programmed frequency band, otherwise the selection is not possible. This key is also
used to program and select the memory channel M1 (refer to item .11). If the UK (United Kingdom) frequency band has
been programmed, by shortly pressing this key you can select the UK channels (UK frequencies) or the CE channels
(CE frequencies).
7. SCAN and M2 Key
By pressing the SCAN key, the SCAN (automatic scanning of busy channels) function is enabled. To enable the SCAN function,
first turn the SQUELCH control (19) clockwise, until the background noise is cut. Then press the SCAN key, radio will
automatically start scanning all channels continuously and the SCAN icon (C) will appear on the LCD. Auto-scan stops if a signal
is detected on a channel, in order to let the user listen to the incoming signal and will start again when no signal is detected on
that channel. If the PTT Key (27) is pressed within 5 seconds, radio will remain on that channel, otherwise scanning will start
