SAFETY NOTES fdgbsddg
The human body should always be separated from the indoor antenna of the Amplifier by at least 25 cm (10”).
Don't expose this product to extreme high or low temperature. For example, putting the Amplifier under direct sunshine for too long may
cause it to overheat, thereby damaging the electronic components inside.
There are no consumer serviceable or modifiable parts inside this Amplifier product. Alteration or abuse of the Amplifier or
other components will void this product’s warranty, and could be dangerous to the user.
NOTE: The wireless amplified can also be used for boat and other applications, but not recommended for small vehicles since
there is no enough separation between inside and outside antenna.
INSTALLATION INSTRUCTIONgbsddg
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.
STEP 1. Install the CM2020 65 dB 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 either
800MHz or 1900MHz 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.
Safety Warning:
1. The input voltage for the Amplifier is 9V. DO NOT use this Amplifier with a regular 12V power supply. If a 12-volt power
supply is connected directly to this Amplifier, it will be damaged.
2. Never plug in the power supply to the amplifier without the outdoor antenna and indoor antenna cables having been attached
to the amplifier.
3. Ensure that the distance between inside and outside antennas is a minimum of 75 feet for the amplifier.
4. If the Uplink Full light or Uplink Half Light 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.
Amplifier Gain Control
Each Attenuation Gain Switches control a certain level of gain. Each button has a certain dB gain, which is on the top of the amplifier.
Those values are 16, 8, 4, 2, and 1 for the five switches respectively.
TROUBLESHOOTING GUIDE
During operation, if the Amplifier interferes with your radio or other electronic receivers, move the Amplifier further away from those
