current status is online. When the 3.0 light is flashing, it indicates that it is bypass now. 

[TUNE]+[LDN]:

    Automatic/semi-automatic mode switching. When the 1.5 light flashes, it 

indicates that the current mode is automatic. When the 3.0 light is flashing, it indicates that it 

is semi-automatic now. 

[TUNE]+[LUP]:   

The  matching  data  of  the  tuning  network  is  saved  to  the  corresponding 

memory. 

AUTOMATIC SHUTDOWN 

The  tuner  has  automatic  shutdown  function  for  saving  electric  energy,  when  the  function  is 

activated, the tuner will turn off automatically if no key is pressed in about 3 minutes. Because the 

tuner  uses magnetic latching relay,  the current  tuning state will not be affected after the tuner is 

turned off.

 

In shutdown state, press on the [TUNE] key, and then press [POWER] key to boot, you can open 

or  close  the  function,  When  the  1.5  light  blinks  once,  it  indicates  that  this  function  is  activated. 

When the 3.0 light blinks once, this function is turned off. 

THE FLASHING OF THE INDICATOR LIGHT WHEN STARTING UP 

When the mAT-125E is powered on, the LED on the front panel flashes to indicate the settings for 

the current tune. 

1.5:    If  flashing  once,  indicating  that  the  current  is  semi-automatic  mode.  If  flashing  two 

times, indicating that the current mode is automatic. 

2.0:    If  flashing  once,  indicating  automatic  shutdown  function  closed.  If  not  flashing, 

indicating automatic shutdown function open.   

BATTERY REPLACEMENT 

The  tuner  uses  two  18650  lithium  batteries  with  a  recommended  capacity  of  2000-2500mAH. 

Batteries can be unprotected because the tuner already contains a battery protection circuit.   

When the tuner is first used or the battery is replaced, it must be charged to activate the internal 

protection circuit before it can work properly. 

SAFETY PRECAUTIONS 

Never operate the tuner with its cover removed. Contact with the components inside the tuner 

while transmitting will result in painful RF burns. 

Locate the tuner so that the rear terminals are not accessible during operation. The single wire 

connection may have high voltage while transmitting. 

Disconnect all antennas from the tuner during lightning storms.

 

TRANSPORT 

Because there are two  lithium batteries  installed inside  the tuner, Please comply with local laws 

when transporting. It could be banned from air transportation.
