<How to Enter theTest Mode>
1. ManualTest Mode
1Enter the test mode by pressing [0] key while pressing the [1] key and [TALK] when in idle condition.
(Key operation : [0] n[1] n[TALK] )
2The RINGER will ring for 500msec when the test mode is started.
3Measurement mode of consumption current. (42# state. Refer to 2-3).
4Use key input to carry out the various settings.
5Use port inputs to set output from LED terminals.
• How to Release theTest Mode
1Press the [0] , [0] and [#] key.
2Turn OFF the power. (Remove the battery and replace them)
2. MachineTest Mode
1When power on reset is applied while a H (high) is input to the TEST SW (TP43) terminal (IC501 $∞ pin), the RING (Level H,
500msec) sounds.
2Following that, at a timing in which the TEST SW terminal has “ H ” (High) input, there is output of “ L ” 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”
output.
3Set the TX setting to TX OFF.
4The channel is set by voice not by data.
5Use port inputs to set output from LED terminals
• How to Release theTest Mode
1Turn off the power.
2Remove the short plug and turn on the power.
