INSTALLATION INSTRUC TION gbsddg
Warning: Never power on the unit before completing the installation.
Always refer to the picture on the next two pages. It is there to help you through each step of the installation.
STEP 1. Install the CM2020 on the wall with the mounting kits supplied.
STEP 2. Connect the Inside Antenna to the side that shows “MS”. (Mobile St at ion)
STEP 3. Connect the Outside Antenna to the side that shows “BS” (Base Station): For best performance, please try t o mount the
outdoor antenna at the location where best possible cellular signal can be found. The outside antenna should be located in an area with at
least 12” radius clear of obstructions, and other radiating elements.
NOTE: Keep the separation distance between the inside and outside antennas to at least 75 ft apart to avoid RF oscillation.
If not, then the amplifier gain must be reduced accordingly using dip switches on both side of the unit for both uplink and
downlink, both PCS and Cellular band.
STEP 4. Connect the Power Cord.
Warning: To prevent damage to the Amplifier, before you plug in to an AC power outlet, please make
sure that both sides are already connected with the RF cables from both the outdoor and indoor
antennas.
WARNING: after power is on, before making any cellular phone calls, if uplink lights
that marked “full” is on (either band), that means the oscillation is happening. You
should POWER OFF the unit immediately, then please reduce both the uplink gain
and downlink gain via the dip switches, or increase separat ion d istance, or do both
until uplink “Full” light of neither bands are on while you are not making cellular
phone calls.
Note: 1. Power lights should always be on after you power up.
2. During Cellular phone conversations, it’s normal to see uplink “Full” light of either or both bands blinking.
STEP 5. After resolving all oscillation problems, users can make cellular phone calls to test how the repeater system works,
further adjust gain if needed.
Safety Warning:
1. The input voltage for the Amplifier is 9V. DO NOT use this Amplifier with a regular 12V or higher power supply. If a 12-volt
or higher power supply is connected directly to this Amplifier, it could be damaged.
2. Never plug in the power supply to the amplifier without the outdoor antenna and indoor antenna cables been attached to the

amplifier first.
3. Please ensure that the distance between inside and outside antennas is a minimum of 75 feet.
4. If the Uplink “Full” light of either band is on when you are not making cellular phone calls, DO NOT use the amplifier; turn it
off immediately, since it may cause damage to the amplifier.

Dip switches are used to adjust the gains on all four links. Each attenuation switch, when turn on, add certain amount of signal loss, the
exact dB values of each dip switch is marked on the side of the dip switches. Those values are 16, 8, 4, 2, and 1 dB for the five switches
respectively.
TROUBLESHOOTING GUIDE
During operation, if the Amplifier interferes with your radio or other elect ronic receivers, move the Amplifier further away from th ose
