CM2100 62dB Manual

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 amplification gain must be reduced with gain control switches on both sides of the unit for uplink and downlink.
STEP 5. Connect the Power Cord.
STEP 6. Turn the Power Switch on
Warning: To prevent damage to the Amplifier, before you plug in the Amplifier to an AC power outlet,
please make sure that both sides are already connected with the cables from both the outdoor and
indoor antennas.
WARNING: after the power is turned ON, and before making any cellular phone calls, if the
warning light is ON, oscillation is happening. POWER OFF immediately, then reduce both
the uplink gain and downlink gain via the gain control switches on the side panel, or further
increase separation distance between the two antennas, or do both until the power warning
light is not ON when you are not making cellular phone calls.
Note: 1. Power lights will always be on after you power up.
STEP 7. After solving all oscillation problems, users can make cell phone calls to test how the repeater system works, adjusting
the gain as needed.
