Equipment description

Front panel button definition

A. PA function key，in the “BYPS” state, press the key, enter the “INUSE” state; in the “INUSE” state, press the key to enter the “BYPS” state
B. Band set button, press the button can set the LPF band and working mode
C. ATU function key, when the ATU display “BYPS” mode, press the button to enter “INUSE” mode, ATU function to open
D. Switch machine button / remove the protection function key / force tuning key， function description: press the key for a long time, for the switch function； in TX mode, press the key quickly, you can force the tuning; in protection mode, press the key quickly, you can remove the protection
E. Screen display

Display information description

A : input SWR display
B : supply voltage display
C : PA operating current
D ：PA temperature display
E ：output SWR display
F ：Input power display，maximum input power is 8W
G ：PA display (“BYPS” represents the current state in the through state, without PA access, “INUSE” represents the current state in the amplification, PA access)
H : When the status of the work shows RX, said the host into the receiving mode, when the state of work shows TX, said the host into the transmit mode
I ：LPF band display，”XXm AUTO” representation band automatic recognition mode（when the band output voltage of host is consistent with form “Band voltage parameter” described in paragraphs voltage，you can use this mode of operation） “XXm MANUAL” means that the LPF working state is in manual operation. “XXm” means that the current band.( when the band output voltage of host is NOT consistent with form “Band boltage parameter” described in paragraphs voltage, you can use this mode of operation, you can manually set the working band of the machine)
l The form “Band voltage parameter”, please refer to page 8.
J : ATU working status display, “BYPS means no access to ATU”, “INUSE” means that the access to ATU(when the SWR is too large, it will automatically be tuned.)
K : Output power display, maximum output power 150W

Protection interface description

A. Warning message number
B. Warning information
ERR:1 input power High

Equipment operation instructions

Connect the power line, the communication line and the input signal line, after the confirmation, turn on the XPA125.

PA functional instructions

Press the PA function button (press once again to close the PA function)
Screen display PA access
Press the transmit button of the host (such as X108G, X5105).
Output power can be observed (antenna to keep matching)

ATU function instructions

(applicable to the case which antenna and the band does not match )

Press the ATU enable button (press the button again to close the ATU function)
Set your host (such as X108G) to CW mode, power set to 5W
Press the CW key, keep tuning until the tuning end

Band selection

Press the Band key (AUTO: automatic mode, according to the band voltage automatic identification band, MANUA: manually set the band, this menu using cycle mode).

Warning release

Release the host’s send button
Observe the warning content (according to the actual situation to deal with related issues)
Press the warning release button (the power button) to remove the warning. For example

General troubleshooting

The following points out the troubleshooting for the general problem, if you still can not solve the problem, please do repair, please do not disassemble the machine, or you will lose the warranty.

Fault description	Possible reasons	Resolvent
Unable to turn on your X108G	No connection power cord	Connecting power cable
Power is not turned on	Turn on the power
