Troubleshooting
The MUGAPLM will not program a PIN Number.
The PIN Number is the same number as the factory’s
reset code. Choose another number.
Intercom cannot be programmed.
The MUGAPLM has an automatic “Lock-Out” feature.
Enter the Master PIN Number followed by “05” then
the residence number (00-63) to enter Learn Mode
for one minute. Within 20 seconds, hold down both
buttons on a Flush Mount Intercom or the Learn
Button on an Access Portable Intercom for 1 second.
You should hear a beep within 10 seconds as
Intercom learns network code. After hearing double
beep, press the Call Button on MUGAPLM to ensure
intercoms have been programmed.
GCU does not function.
Ensure GCU has been programmed to the
MUGAPLM (see GCU: Program). If MUGAPLM
beeps 4 times it means the GCU was not
programmed to the MUGAPLM. If GCU has Identity
of 2, 3, or 4 make sure the corresponding Identity is
set with Dipswitches 1 and 2 in GCU (see GCU
Installation).
Manufacturer’s Reset Code is needed to reset
MUGAPLM.
The MUGAPLM’s serial number is printed on the
inside of the MUGAPLM’s back panel.
Call Technical Support at 1-800-528-2806 for Reset
Code. You MUST have MUGAPLM’s serial number to
receive the Reset Code. The MUGAPLM will clear its
memory and can be reprogrammed.
When a call is made, two devices respond.
The two devices were programmed with the same ID
number. Both devices will ring until the call is
answered by one of the devices and a connection is
made.
An error tone is heard when GCU is activated.
The MUGAPLM is not communicating with GCU. The
GCU may be out of range or not programmed
correctly. If GCU and MUGAPLM function when close
together, the GCU may need to be mounted higher
off the ground or on a different surface. Metal, trees,
or masonry cause interference.
If MUGAPLM and GCU do not function when close
together, the GCU has not been programmed to the
MUGAPLM. Check the GCU’s Identity and reprogram
it (see GCU Assemble and Program).
There is a buzzing noise or failed connection
when used with the OTIU or MUOTIU.
Move the OTIU/MUOTIU away from computer or
phone. Changing the channel of OTIU/MUOTIU and
MUGAPLM can also solve problem (see Operation &
Features: Alternate Channel Selections).
When used with OTIU or MUOTIU only first couple
of words from caller is heard.
Lower MUGAPLM microphone sensitivity (see
Operation & Features: Microphone Sensitivity).
System has a very short range.
Interference from a conflicting 900Mhz radio
transmitter can affect range. Change the channel of
MUGAPLM (see Operation & Features: Alternate
Channel Selections).
When used in buildings with stucco or cement walls,
the range is greatly reduced. Repeaters can be used
close to the building to solve this problem.
