HANDSET
[Start-up method] 1. Starting with POWER ON � Reset the POWER ON with TEST SW pin (IC501 #� pin) in �H� status, and the Test mode starts. 2. Starting from Idle status � In the Idle status, press [TALK] , [0] and [7] keys at the same time, and the Test mode starts. 3. Operation at start-up � When the Test mode starts, the Handset causes the ringer to sound for 500ms, sets a channel depending on the key matrix condition so as to be ready for receiving. Also, the Handset sets the Liquid cristal display all turn on, the RSSI gain to High, and goes in the Test Mode Idle status. � For the COL0~COL3 logic of key matrix and channel setting, refer to the frequency table.
[Dial � Auto Hold Reset � Charge Test] � This mode is activated when [REPEA T] key is pressed in the Test Mode Idle status. 1. Dialtest Each time [REPEA T] key is pressed, the following dial signals are transmitted: �0� of PULSE � �1� of DTMF � �#� of DTMF � 2. Hold reset test The ANSWER LED turns on when the hold reset detection port is in �High� status, or turns off when �Low�. (Once the �Low� is detected, �Low� is kept during the Test mode.) 3. Charge detection test The CHARGE LED turns on at Charge ON, or turns off at Charge OFF.
[Operation in Test Mode Idle status] 1. RSSI monitoring � The RSSI is always monitored at IC501 $� pin (SIG-IN). (RSSI is present: SIG-IN = �Low�, RSSI is not present: SIGIN = �High�) 2. [RING ON/OFF] switch monitoring � In the Test mode, the RING MODE port is always monitored at IC501 7 pin (RING MODE), and if RING is ON (RING MODE = �High�), the buzzer volume is increased, or if RING is OFF (RING MODE = �Low�), the buzzer volume is reduced. 3. Key input monitoring In the Test Mode Idle status, key input is always monitored, and a key touch tone is generated each time a key is pressed, then respective modes are activated according to the key pressed.
