User Manual of ZZQ-8A Repeater
I-Summary:
Repeater is a TX/RX device repeating the RF signal. The RF signal should be:
1) Same frequency to the repeater.
2) Oscillating resistor should be matched with repeater.
This repeater supports PT2262/1.2M, PT2262/2.2M, PT2262/3.3M, PT2262/4.7M,
PT2240/1.5M (IC/OSC), and it has learning function, up to learn 100 pcs transmitters. So it
can repeater the one learned, to avoid others transmitters.
II-Technical Data:
- Working frequency: 315/433.92MHz.
- Working voltage: DC12V.
- Standby current: 30mA.
- Working current: <255mA.
- Receiving sensitivity: -108dBm.
- Transmitting power: 500mW (transmitting distance is about 1500m in the open area).

- POWER indicator: power indiction
- SEND indicator: Repeating indication, it will be on while transmitting signal.
8 gang DIP switch: At the bottom of the housing, each gang has on/off status. The
instruction are below:
1-gang: ON position means repeating signal of PT2262/1.2M. OFF position has no function.
2-gang: ON position means repeating signal of PT2262/2.2M or PT2240B/1.5M. OFF
position has no function.
3-gang: ON position means repeating signal of PT2262/3.3M. OFF position has no function.
4-gang: ON position means repeating signal of PT2262/4.7M. OFF position has no function.
5-gang: Adjust repeating time - OFF position mean 1.5s, ON position means 3~5s. (ON
position is stable position. OFF position is multiple transmitters mode)
6-gang: Transmitter selection - ON position just repeats the learned transmitters (If there
are more than 2 repeaters in same place, please use this function). OFF position can repeat
all the signal which match with it.
7-gang: When it learns transmitter, please switch to ON position, or not, turn to OFF
position.
8-gang: Testing function - Turn to ON position, the device always transmits the signal of
PT2262/1.2M. When it is working normally, turn to OFF position.

IV-Operation:
1) Install antenna: Please install the 2 antennas to the device when
first time use. (No order)
2) Deploy repeater: Please put the device in the middle between
transmitter and receiver and adjust well the distance according the
signal of transmitter. When it is ready, please also adjust the
receiver well.
4) Learn transmitter: Turn 6-gang, 7-gang to ON Position. Select the right regular from 1-4
gang. Then trigger the transmitter, the SEND indicator LED flick twice, it shows the learning
finished. When all the transmitter learned, turn to 7-gang to ON position, this repeater
works and just transmits the learned transmitter.
5) Delete transmitter: Before power on the device or in 15 seconds after power on. Turn 7-
gang and 8-gang to ON position. The SEND indicator LED flick 3 times. All the learned
transmitters are deleted.
V-Notice:
3) Set working mode: Connect to DV12V power supply, the POWER indicator LED will be on,
the repeater goes into working status. Adjust the DIP switch to select transmitting signal.
1 gang to 4 gang means transmitting siganls. (Note: Ther is only 1 gang allowd to be ON
position when it is working. If all the first 4 gangs are in OFF position, it repeat signal of
PT2262/4.7M)

1) Install the antenna to upwards, and do not put it near the metal things and wall.
2) This device is not waterproof.
3) If receiver cannot receive signal, please adjust distance between repeater and
transmitter, up to the repeater can receive the signal from transmitter, and then adjust the
receiver to the repeater.
4) Power supply is DC12V, output current is no less 300mA.
5) Before power on this device, please make sure 7-gang and 8-gang are not in ON position
at same time, or it will delete all the learned transmitters.
