3. Installation and Operation

1) Connecting power
Connect the DC18V transformer (included, no polarity) to +/- connectors on the rear of the master station correctly. Depress the power switch. Year, month, day and time will display on the LCD. The power is in normal working status.
2) Testing master station and substation
Testing master station: Depress the power switch on the panel of master station after connecting it to power source. The master station will start self test and test each substation one by one from No. 1 substation. Corresponding indictor light will flash one if the tested substation is in normal working status. And the indicator light will lighten and keep in bright green if otherwise. After testing all substations, the bright green indicator light will go out after five seconds. The master station will return to normal status automatically after testing.
3) Alarm and talk
Corresponding router indicator light of the master station will flash in red if a substation is calling. And calling substation number will display on the LCD, music prompt will sound and the system will broadcast calling number. You can talk to the calling substation by depressing corresponding router switch on the master station, picking up microphone and substation. (Note: Master station can talk by depressing the hands free key; Master station can listen by releasing the hands free key. Talk from master station can be heard by substations after 0.5 second by using hands free key for the first time.)
4) Monitor and circular monitor
Monitor: Depress the router switch on the panel of master station to monitor corresponding substation. Eject the router switch to cancel.
Circular monitor: Depress the monitor switch of master station in standby status for two seconds to monitor substations circularly (each substation will be monitored for five seconds). Depress the monitor switch again for two seconds to cancel circular monitor.
5) Group call, all call
Group call:
Select No.1-5 substations by picking up handset and depressing No. 1 router switch of master station for two seconds. Corresponding indicator lights will lighten in green. The master station can talk to all selected substations with handset at this time. Depress the No. 1 router switch of master station for two seconds again to cancel.
Select No.6-10 substations by picking up handset and depressing No. 6 router switch of master station for two seconds; select No.11-15 substations by picking up handset and depressing No. 11 router switch of master station for two seconds (by analogy). Follow above method to cancel.
All call:
Press the broadcast key on the master station to select all substations. The master station can talk and broadcast to all substations by picking up handset or depressing hands free key.
