<How to Enter the Test Mode>
1. Manual Test Mode
1 Enter 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] )
2 The RINGER will ring for 500msec when the test mode is started.
3 Measurement mode of consumption current. (42# state. Refer to 2-3).
4 Use key input to carry out the various settings.
5 Use port inputs to set output from LED terminals.
• How to Release the Test Mode
1 Press the [0] , [0] and [#] key.
2 Turn OFF the power. (Remove the battery and replace them)
2. Machine Test Mode
1 When 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.
2 Following 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 PLL setting to the CH which was read to with the CH setting terminal according to that “ L”
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

• By pressing the CH key there is increment of the channel. However, this does not include the test channel.
• Control of the power source during 38# DATA TX is (TX&RX RF&RX AF=ON) in 44# state.
• Control of the power source during the 70# key check mode is 41# state (TX OFF).
• For CH setting, SIGOUT control and power source control (with the exception of above-mentioned 38# state) the state can be set indepen-
dently.
Example : In 15 ch, the order for carrying out TX modulation level and RSSI (H) sensitivity setting is as follows :
The following are possible : 15# n 44# n 36#
36# n 15# n 44#
