Installation Instruction:
Step 1
Install the CT-SAMM modulator into its corresponding rack chassis. Be sure to align the module
using the rack chassis guides to ensure the CT-SAMM is properly seated for grounding.
Step 2
Connect the 3-pin power plug from the power supply harness to the power jack in the
rear of the CT-SAMM modulator. Only use the wiring harness that is for your
power supply. Using a non-compliant wiring harness will void the warranty.
Step 3
Allow at least 15 minutes for the modulator to reach a stable operating temperature
and stable output. Do not attempt to adjust before the warm up period since the modulator
output will change as the unit comes to the operating temperature.
Step 4
If needed, toggle the CATV/VHF UHF switch to select between cable TV and
off-air channel assignment.
Step 5
Select the desired channel by pressing either channel button adjacent to the arrows on
front panel. If the channel exceeds 100, The LED light will be on at the “+100 “ mark.
Step 6
When the desired channel is displayed, press the set button to lock channel and the LED light
will be on at the “LOCK ” mark.
Step 7
Connect an RF signal meter using dBmV or an RF spectrum analyzer to the “RF OUT”
port of the CT-SAMM to balance and ensure the desired RF output level.
