3. Operation
3.1 Introduction
This section provides information for operating the HR1900P repeater.
3.2 Operating Instruction
3.2.1 Power-up
Connect the repeater to AC/DC Adaptor. If no FAIL condition is present, only the
“POWER” LED will remain lit. The repeater is then operating properly.
3.2.2 Fail Status
3.2.2.1 Overdrive Fail
There is one overdrive fail on the unit, for the uplink. Over driving occurs when the RF
output power of the repeater exceeds a prescribed limit. This means that the input RF
power level is too high, or the repeater is oscillating. The condition may be transient,
caused by a passing emergency vehicle emitting a strong signal for example, or
permanent, due to a nearby base station. It may also indicate low isolation between the
antennas, which causes the unit to oscillate (please refer to the section 2.6.2 of this
manual for antenna alignment and isolation.)
The overdrive fail on the HR1900P repeater is design to detect whether the over driving
is transient or permanent. If the output power level of uplink exceeds prescribed
limit ,then uplink is disconnected and the FAIL LED(RED) is on. Repeater automatically
checks output power level every 1 minute of a 5 minutes cycle when uplink has over
power. If uplink still exceeds level then shut down mode continues for another 10
minutes. After 10 minutes, uplink is switched on again and it checks output power level
again. (Repeaters the process)
4. Trouble Shooting
If the repeater does not operate properly after installation, first make sure that the
installation procedures as described in section 2 of this manual were followed correctly.
Inspect each connection, both RF and AC, and connectors for a secure fit, checking to
see if all the connections are made to the proper ports of the unit and the antennas.
If the malfunction is due to an alarm condition, refer to the appropriate part of the
section 3.2 of this manual. Corrective actions may be taken for the overdrive alarms.
