TEST MODE
BASE UNIT SECTION
MANUAL TEST MODE
Set the Test Mode:
1. Set the DIAL MODE switch to “P” (pulse).
2. While pressing the HANDSET LOCATOR key, insert theAC
adaptor (Reset start).
3. With the HANDSET LOCATOR key, still held down, switch
the DIAL MODE switch “P” (pulse) n“T” (tone) n
“P” (pulse).
4. When the HANDSET LOCATOR key is released, test mode
starts.
5. Firstly, “0” will be dialled out at 10 pps. Then “1”, “4”, “8”
and “#” will be sent out by DTMF.
6. Set to TX ON. Goes to external line state in 1 CH.
Release the Test Mode:
1. Pull out the AC adaptor or turn off the power.
MACHINETEST 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.
Release the Test Mode:
1. Pull out the AC adaptor or turn off the power.
2. Remove the short plug and turn on the power again.

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 n1 nTALK )
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 $º 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 PLL setting 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.
