WARNING:
••
Disconnect operator power before any installation or repair
••
Always wear safety glasses
Your Digi-Code radio controls are designed specifically to remotely control a garage
door opener and to give years of trouble free service without adjustment.
Because all
radio controls are set with the even numbered switches in the “ON” position when
they leave the factory, it is recommended that a different code be selected and set at
the time of installation.
Please refer to the “Setting the Code Switch” section for
instructions. The radio frequency (RF) portion of the controls, however, are tuned to
standard frequencies and are thoroughly tested at the factory. This permits the addition or
replacement of either the transmitter or the receiver by specifying the Model number and
the RF frequency designated on the identification label. RF adjustments are not needed
nor should any be attempted.
SECTION #1
ACCESSING THE CODE SWITCH AND BATTERY COMPARTMENT
The models 5040, 5042, 5050 & 5052 mini transmitter cases are made up of two halves
which are held together by a small phillips head screw. Removing this screw will allow
access to the code switches and the battery compartment ( see diagram #1 ).
