1.7.3 Required Power Supply for Transceiver

The radio operates on a DC voltage of 28 V DC (28 V DC to 29 V DC). This voltage is pro-
vided as an option by the external R&S IN4000A Power Supply (19" rackmount of 1 height
unit, see Figure 1.4) available for the purpose. The connecting cable between radio and
R&S IN4000A is available on demand. The radio may also be powered by an external battery
(19 V DC to 31 V DC). An automatic switchover facility integrated in the radio provides for
automatic standby switchover in case primary power fails.
