SIGNAL MODE ADJUSTMENT AND SETTING

Perform the signal mode setting before the final installation or wiring work because the

setting requires the removal of the top cover.

Remove side plate screws (four places).

Detach the top cover.

1. RECEIVING SOUND VOLUME ADJUSTMENT

The receiving sound volume can be adjusted in 8dB steps by switching SW3 setting

as shown in the figure below.

Position of SW3 is factory-preset to "1".

2. ADJUSTMENT OF CURRENT SUPPLIED TO TELEPHONE

The distance between the TD-600 and telephone can be made greater by making switch

positions of both SW1 and SW2 identical to adjust the current to be supplied to the

telephone. See the table below.

The line loop resistance is factory-preset to 0~1500

4. POLARITY REVERSE SIGNAL CONTROL

When connecting the telephone line terminal to equipment that must not receive the polarity

reverse signal, install the jumper wire in place marked with JP4 in the figure.

Jumper JP4 is not factory-preset because the polarity reverse signal is set to transmit

from the CH1 or CH2 telephone line terminal.

CALL OPERATIONS

(1 )Lift up the handset and confirm that a dial tone is audible. Dial the desired station number

within 10 seconds.

(2)Replace the handset when terminating the conversation.

(3)The intercom station's dial key

[Example]

Intercom station

(All call paging)

• Dialing must be completed within 10 seconds after lifting up the handset. If incomplete,

no dial signal can be transmitted to the exchange even when the dial keys are pressed.

Thus, the pushphone cannot be used for functions such as call transfer, speech message,

busy call back etc. to dial during the conversation.

• When transmitting the DTMF signal during the conversation in conunction with the TI-20

or TI-600 tie-line unit etc., do not press any button of pushphone. This will lead to

malfuction of the exchange.
