Mechanical Interface Description

Danger of electric shock!
The radio contains a two-pole or neutral-conductor fuse. This means that
some parts of the radio will continue to be energized after the fuse has been
tripped.
When replacing the fuse, always disconnect the radio from the AC power
supply. Do not touch any live parts when performing service and
maintenance on the radio while the radio is switched on (by qualified
service personnel only).
Before putting the transceiver into operation, make sure that the following
minimum requirements are met:
 Antenna is connected
 Press the POWER switch on the front panel.
The following LEDs should go on:
LED AC lights up when AC-Supply is connected to X1.
LED DC lights up when DC-Supply is connected to X2.
Display shows booting progress. After successful booting the screen
changes to the standard operating display.
LED VOP lights up after successful booting and shows that the
transceiver is active.
LED GO lights up after successful booting and shows that the
continuous built-in test could not detect any CBIT errors.
Note: If fuse F1 or F2 in the AC line input or fuse F3 in the DC line input is
defective, please replace it with the fuses listed in the appendix Fuses. If
the fuses get defective again after the replacement, please contact our
service center.
Note: Deviating from the requirement stated in section 4.3 "Warm up" of the
European standard ETSI EN 300676-1 V1.5.1 (2010-07), it may take the
radio longer than one minute to start and to reach the parameters required
by the standard.
Note: See Mechanical Interface Description in the Appendix.
