You have the 'squawk' turned up too far. This will be a standard dial or a small slotted dial inset in the body. Turn counter clockwise to lower the resonance effect. This should not be confused with a transponder squawk code, which is a different thing totally. If your model is more up to date then the squawk function will be automatic and toy will need to reset it by firstly switching the unit off, then hold the transmit button and the volume UP button while powering the unit on. This will reset all the functions of the unit back to the factory default. If you still have problems then the unit is faulty and needs repair or replacement.

Hi,

D23 is the reverse protection diode and it shorting is the primary reason your fuse blew. As you posted, power was applied in reverse, hence other components would also fail. Pls check:
1. D22 - 9.1V Zener Diode
2. TR23 (2SC1096) 9 Volts regulator
3. D19 - 5.1 Zener Diode
4. IC4 (TA7222) - Audio Amp
5. TR14 (2SC2029B/10) - Finals
6. TR15 (2SC2028B/20) - Driver
7. Most capacitors over 220uF (like C123, C114 & C112)

Hope that this be of help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

been received.
##0670 [Tx] at time of V.8 late start, the V.8 ability of DIS front the receiving party is expected
to be detected, and the CI signal is expected to be transmitted in response; however,
the procedure fails to advance, and the line is released because of T1 time-out.
##0671 [Rx] at time of V.8 arrival, procedure fails to move to phase 2 after detection of CM
signal from caller, causing T1 time-out and releasing line

Changed battery and still does not work - hear pinging in computer


There are buttons on the transmitter/receiver and the mouse(small red on bottom). Turn off the mouse. Plug in the USB Tx/Rx and hold down the button. Then press the red button on the mouse and hold for one second. Do this until the rapidly flashing light on the Tx/Rx slows down. The unit's frequencies are then encoded/decode and can communicate.
