1. BS: Donor antenna
2. MS: Service antenna
3. Power supply indicating light: Lightening, the repeater switches on the power. Out of light, the repeater switches off
the power.
4. DCS / PCS / 3G UMTS WCDMA uplink gain adjustment switch:
5. DCS / PCS / 3G UMTS WCDMA downlink gain adjustment switch:
6. CDMA / GSM uplink gain adjustment switch:
7. CDMA / GSM downlink gain adjustment switch:
Switch moving up as 1 makes gain attenuation, while switch moving down as 0 makes gain remain original. Factory default
setting: all switch down. For example, when switch 1 and switch 4 move up, the corresponding truth table attenuates 9dB.
1. DCS / PCS / 3G UMTS WCDMA downlink signal indicating light:
When BS connection port receives DCS / PCS / 3G UMTS WCDMA signal which surpasses -60dBm, indicating light
lightens or twinkles. Now the device receives well and is able to meet the coverage requests.
2. CDMA / GSM downlink signal indicating light:
When BS connection port receives DCS / PCS / 3G UMTS WCDMA signal which surpasses -60dBm, indicating light
lightens or twinkles. Now the device receives well and is able to meet the coverage requests.
3. DCS / PCS / 3G UMTS WCDMA uplink signal indicating light:
When BS connection port receives DCS / PCS / 3G UMTS WCDMA signal which surpasses -60dBm, indicating light
lightens or twinkles. Now the device receives well and is able to meet the coverage requests.
4. CDMA / GSM uplink signal indicating light:
When BS connection port receives DCS / PCS / 3G UMTS WCDMA signal which surpasses -60dBm, indicating light
lightens or twinkles. Now the device receives well and is able to meet the coverage requests.
ATTENTION: Just one band is occupied when cell phone is working, therefore, in general usage of dual band repeater, only
downlink and occupied band for uplink indicating lights illuminate.
7.4. System Test
7.4.1. Check whether the coverage is good
1. Take a test with a mobile phone or a data card (engineering mobile phone is preferred). If the signals in most areas
have not been improved, please check recommendations below again:
- Weak input signal leads to low output power. To increase input signal power level, change the direction of the
outdoor antenna or its installation position or replace it for an antenna with higher gain.
- Check whether it is necessary to use additional indoor antennas as barriers block signal penetration; also check
whether the repeater's power is enough; please install extra indoor antennas or replace the repeater for another
model with higher power level.
2. If the signals in small parts of the area have not been improved, please check the following:
- Check whether the indoor antenna is installed correctly or not; you may try to change the antenna location to
