Safety Precautions
Opening the APEX 1900-24 equipment could result in electric shock and may cause severe injury.
Connect the equipment frame ground to the building ground.
Operating the APEX 1900-24 with antennas in very close proximity facing each other can lead to
severe damage to the repeater.
RF EXPOSURE INFORMATION
A minimum separation distance of 7.9 inches (20cm) must be maintained between the user and the
external antenna of the repeater to satisfy FCC RF exposure requirements. For more information
about RF exposure, please visit the FCC website at www.fcc.gov
This equipment is for indoor use only and enables the communication wiring to communicate inside
the building.

AGC (Automatic Gain Control)
AGC feature prevents the repeater from exceeding its maximum output power by reducing the gain
automatically. AGC is used to adjust the gain to an appropriate level for a range of input signal
levels
.
ASD (Automatic Shutdown)
ASD does not:
1. prevent oscillation
2. protect from excessive input.
ASD helps protect the amplifier from over load. ASD helps protect the network by preventing
excessive signal output power.
There are three parameters: ASD Level, ASD Time, and ASD Iteration.
If the output power exceeds higher than the “ASD LEVEL”, the repeater will shut down for “ASD
TIME” seconds and it will turn the amp back on to measure the output power again. If this repeats at
“Iteration” times, the repeater will shut down completely.
1. Introduction
APEX1900-24 is used to fill out areas in APEX1900-24 systems, such as base station fringe areas,
business and industrial building, etc.
APEX1900-24 receives signals from a base station, amplifies and retransmits the signals to the
mobile stations. It also receives, amplifies and retransmits signals in the opposite direction. Both
directions are served simultaneously with the following features:
