Keypad
1. Enter the digits desired through the
keypad by firmly pressing one keypad key
at a time. Each keypad press should be at
least 1/2 second duration.
Note: The minimum length of time a signal should
be sent is 1/2 second. Too short of a signal
may prevent proper digit recognition by the
system decoder.
2. Listen for the sidetone as each keypad
key is pressed. The sidetone will be
heard from the radio speaker.

two-way radio operation mode.
TIPSFOR USING THE
MICROPHONE/RADIO
Whenever possible:
• Place your calls in areas of optimum
system coverage (full quieting). Calls
made in noisy (fringe) areas may not
connect.
• Make your calls when the vehicle is not
moving – parked, at a stop sign, or at a
traffic light. Dialling (pressing keypad
keys) while driving can distract the driver
(a safety hazard). Dialling while driving
also reduces call reliability by promoting
the chance of a weak signal due to
“dead spots” or automobile/traffic noise
interference.
SERVICE
The MDRMN4026 Enhanced Keypad
Microphone is not repairable. Order
replacement microphones as required.
