INSTALLATION INSTRUCTION
gbsddg
Warning: Never power on the units before completion of the installation.
The signal is received by the outside antenna from the cell tower, then AMPLIFIED and transmitted to your phone through the inside
antenna. When the phone transmits, the signal is received by the inside antenna, then AMPLIFIED and transmitted to the cell
tower through the outside antenna.
Always refer to the picture on the next page. It is there to help you through each step of the installation.
STEP 1. Install the CM800 on the wall with the mounting kits supplied.
STEP 2. Connect the Inside Antenna to the side that shows “Indoor Ant.”.
STEP 3. Connect the Outside Antenna:
Select an outside mounting location. For best performance, try to keep the antenna on top
of the roof. The outside antenna should be located in an area with at least a 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 amplification gain must be reduced with gain control switches on both side of the unit for
uplink and downlink.
STEP 4. Connect the Power Cord.
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 power is on, and before making any cellular phone calls, if uplink
lights marked either “full” or “half” is on, that means that the oscillation is
happening. A full light means severe oscillation, a half light identifies that there is
some level of oscillation. You should then POWER OFF immediately, then reduce
both the uplink gain and downlink gain via the gain control switches, or further
increase separation distance, or do both until neither of the uplink light are on
when you are not making cellular phone calls.
Note: 1. Power lights for both uplink and down link will always be on after you power up.
2. During Cellular phone Conversations, it’s normal to see both uplink half light and full light turn on and off
.
STEP 5. After solving all oscillation problems, users can make cellular phone calls to test how the repeater system works,
adjusting gain as needed.
