upon the configuration) the
idRU weighs between 20 and 38 kg (44 and 84 lb).
If the new unit is of exactly the same model and configuration as the previous unit, the Clone option can be
used to transfer the configuration from the suspect unit to the new unit after the physical installation.
To replace the idRU-40
1. Record the serial number and four-digit identification of the suspect repeater – located on the label at
the side of the repeater. This will be needed when shipping the repeater for service.
