6) Up and Down keys
If you depress briefly the keys Up and Down ( 4 ), the corresponding values
( volume, channel ) are changed for one step up or down. If you hold these keys for
1 or 2 seconds, the values change quickly into the corresponding direction. Some
values run in a ring like system, others remain constantly after they have reached the
highest or lowest value. In this case you will hear from the speaker a triple confirma-
tion tone.
7) Socket for external earphone-microphone
The socket ( 2 ) ( ø 2.5 mm ) on the top side of the unit can be used to connect an
external earphone-microphone, e.g. ORM-MS. While the socket is used the internal
speaker ( 6 ) and the internal microphone Mic ( 7 ) are switched off.
8) Battery indication
In case of completely charged batteries the battery symbol ( position D ) is filled-
in. At 4.9 V supply voltage one third of the filling disappears, at 4.6 V one other third,
and at 4.1 V there is only the frame remaining. Now it is time to change or charge the
batteries, otherwise errors of functions and displayed information may occur. The cur-
rent consumption in transmit mode amounts to 270 mA ( PMR mode ), 110 mA ( LPD
mode ), in reception mode with closed squelch 40 mA and in power save mode 15 mA.
