inside the board.
• Check the red and orange wires, make sure they are soldered into the
speaker.
• Turn the power "OFF" and disconnect the speaker connector from the board.
Set your meter to Ohm and use 50 Ohm scale or higher. Put the two probes
into the speaker (+) and (-) (polarity not important) and the meter should read
between 19 - 24 Ohms.
• Check the phone line using a standard phone, make sure you get dial
tone.
• Check the speaker and microphone connection. The snap on clip connector
on the speaker and microphone connector must be facing inside the board.
• Check the red and orange wires, make sure they are soldered into the

• Turn the unit power "OFF" and "ON".
• Erase the memory chip (EEPROM) using Function Code 50. If you have
trouble to log on to programming mode, press and release the square red
button then press #.
• The power LED must be "ON" (LED2 marked on the board).
• The Power Switch's toggle must be on the left position ("ON").
• Check the fuse (3 Amp 250 Volt).
• Measure the voltage on AC1 and AC2 (set your voltmeter to AC and put the
probes on AC1 and AC2), it should read within 12VAC-13.8VAC or if you use
12 VDC, the meter must read 13.5 - 14.0 VDC.
• The LCD's ribbon cable has red dots along the side. The red dots must be
facing up. It must be connected to the terminal marked number 1.
