Connect to repeater from PC via OMT.
2. Set Channel No.
z
Keep RF switch ON and set the channel number of the repeater’s
operating frequency.

4. Configure [Equipment ID]
z
Go to [Properties Info] and set [Equipment ID].
5. Comm. Config
z
Enable the power supply by selecting “On” in [RF] -> [Switch]; go to
[Properties Info.] -> [Comm. Config.] and set OMC Phones No. , the
service No. of SMSC, Report Mode.

z
Use test-handset to verify field intensity within the coverage area. If
needed, realign the service antenna to achieve the desired
coverage.

coverage.
z
Note: If during operation, the equipment gain could not be set to
maximum or the output power is not high enough due to insufficient
donor and service antennas isolation, then the antennas’ position
should be changed to increase isolation. If the output power is too
high and ALC is activated, then adjust the DL ATT to achieve
optimal DL Gain.

no interfering BTS
z
Adjust UL gain and perform test calls. Typically, the UL gain is set
around 5dB less than DL gain. Perform test calls in the coverage
area while adjusting UL gain if required.

Note: If the repeater is near the BTS and the test call performance
is poor, this may be due to UL noise interference to the BTS. Users
can calculate and determine if the repeater UL noise will interfere
with the BTS.
