Test radio units
The test software for the test radio unit (test RU) is integrated in the standard
software. A rotary switch is on the bottom of the test radio units so that the test HAs
can identify the test RUs (position 1..8). Rotary switch positions 0 and E enable
normal operation of the test RUs in a system, whereby position 0 switches on
automatic SW upload and position E switches it off. Before changing the rotary
switch, the test RU must always first be disconnected from the power source.
Power supply
The test RUs are designed to be operated with the 12 V lead-acid batteries, but they
can also be operated with the supplied plug-in power supply units. Supplying the
test RUs with power via the AD2 line, however, is not possible. The lead-acid
batteries can be charged while operating the test RUs.
Lead-acid Batteries
The 12 V lead-acid batteries may be charged only with the charging devices
intended for that purpose. For charging, the charging device switch must be set to
the 12 V position. The LED on the charging unit indicates the battery's charge level.
Lead batteries can be stored in the fully charged state.
When the lead-acid batteries are fully charged, the operating time of a test RU is
about 12 hours. When the battery charge becomes low, it is indicated by the test RU
LED (see
Tab.
2).
Note:
Be absolutely sure to observe the "THIS SIDE UP" notice on the lead-acid
battery. During recharging, ensure that the battery is positioned so that
the indicated side is up. This is for safety reasons, since otherwise there is
the danger that the battery could leak out.
Operation with External Antennas
External antennas can be connected to the test RUs for measuring purposes. They
can be activated and deactivated with a test HA. The current state is displayed on
the test RU. (See
