Release the Test Mode:

1. Pull out the AC adaptor or turn off the power.

MACHINE TEST MODE

Set the Test Mode:

1. With one of the CH setting terminals in “H” input state, cause

Reset of Power ON. Equipment enters machine test mode.

2. Setting of CH according to logic input with CH setting

terminal.

3. ON/OFF of TX is according to the input logic of the DIAL

MODE terminal.

MANUAL TEST MODE

Set the Test Mode:

1. Enter the test mode by pressing 0 key while pressing 1 and

TALK keys when in idle condition.

(Key operation 0 t1 tTALK )

2. The RINGER will ring for 500 msec. when the test mode is

started.

3. Measurement mode of consumption current. (42# state)

4. Use key input to carry out the various settings.

5. Use port inputs to set output from LED terminals.

Release the Test Mode:

1. Press the 0 , 0 and # keys.

2. Turn off the power. (Remove the battery and replace them.)

MACHINE TEST MODE

Set the Test Mode:

1. When power on reset is applied while a “H” (high) is input the

TEST SW (TP43) terminal (IC501 r; pin), the RING (Level

H, 500 msec) sounds.

2. Following that, at timing in which the TEST SW terminal has

“H” (high) input, there is output of “L” (low) by the CH

(channel) setting control terminal. Then there is PLLsetting to

the CH which was read to with the CH setting terminal

according to that “L” (low) output.

3. Set the TX setting to TX OFF.

4. The channel is set by voice not by data.

5. Use port inputs to set output from LED terminals.

Release the Test Mode:

1. Press the OFF key.

2. Remove the short plug and turn on the power.
