also be extended to over 70 feet using 2 optional 25-foot cables. Contact a 

Uniden representative for further information.

HARDWARE

The following hardware is included in your UMRMIC kit:
•  UMRMIC microphone with attached coiled cable
•  23-foot extension cable
•  Mounting bracket and screws
•  Protective cap for remote mic jack
•  Hex nut

INSTALLING THE MICROPHONE

1.   Determine where the remote microphone will be located (secondary 

station). Place the remote microphone cable base at that location and 

mark the screw holes and cable access hole. Remove the cable base.

2.   Drill the cable access hole (and pilot holes for the screws if desired).

CAUTION: Be careful when drilling the holes; the type of surface being 

drilled into may require special treatment to avoid cracking or splitting.

3.   Run the cable from the primary station to the secondary station as 

determined in Step 1. Secure the cable as needed.

4.   Align the 23-foot routing cable 8-pin connector labeled “RADIO 

” to 

the radio’s 8-pin connector labeled “

RM.” Connect the cables.

5.  Replace the cable base and insert and tighten the screws.
6.   Insert the cable through the access hole from the back. Insert the rubber 

cap and hexagonal nut.

NOTE: Keep the cap closed when the microphone is not connected.

7.  Securely tighten the hexagonal nut.

CAUTION: Do not over-tighten the hexagonal nut; it should fit snugly. 

Over-tightening it could cause it to break.

8.   Insert the microphone cable’s 8-pin connector into the routing cable. 

Tighten the microphone cable’s round nut, making sure it is a snug fit 

and not too tight.

WARNING: Do not connect or disconnect the microphone when the radio 

is turned on. The radio should be turned off.

OPERATING THE MICROPHONE

The UMRMIC operates the same as the UM725 marine radio series with the 

exception of key placement. The following illustration and table define the 

microphone keys and other operational elements and their purpose.

NOTE:  Since the microphone’s directivity is sharp in order to reduce 

ambient noise, speak directly into the front of the microphone hole.
