When used in buildings with stucco or cement walls,  
the range is greatly reduced. The Repeaters can be  
used close to the building to solve this problem.  
Keep MUOTIU-EX away from trees, metal objects,  
masonry, computers, and any other “Radio Noise  
Source”. Radio devices that run on 900 Mhz also  
affect range. Turn them off and see if reception has  
improved.

Move MUOTIU-EX away from phone and/or

or the channel on the MUGAPLM (see Multi-Unit Gate  
Access Panel manual).  
Troubleshooting  
Dial tone is not heard after connecting to the  
MUOTIU-EX.  
Check phone connections. If it is a two-line phone  
ensure it is on Line 1.  
Only first couple of words from caller are heard.  
Lower the MUGAPLM microphone sensitivity (see  
Multi-Unit Gate Access Panel manual).  
If a dual-tone error tone is heard when trying to open  
gate, ensure MUOTIU-EX is programmed to the  
correct MUGAPLM. Check that gate operator has  
been taught to master unit as well.  
If MUOTIU-EX has already been programmed it will  
need to have memory cleared (see below).  
Memory needs to be cleared.  
Clearing MUOTIU-EX memory will not clear any  
MUOTIU-EX settings or programmed phone numbers.  
To clear memory, dial “**#8” on the telephone  
connected to the MUOTIU-EX. A beep will be heard.  
When dialing numbers a dial tone is heard.  
All numbers and symbols must be dialed within 3  
seconds of each other, otherwise the MUOTIU-EX  
times out and returns to dial tone.
