3.6.2 LEDs on CPU
The CPU is the only board having six LEDs. LEDs 1 to 4 are identical to the LEDs on other boards.
Below the reset button LED 5 and 6 are found.
LED 5
LED 5 on the CPU board is the ‘message-received-LED’. When a message is written in one of the
tables info, fault or service, LED 5 is turned on. The LED is cleared immediately after opening the
appropriate error table menu as it assumes that the reader then takes notice of the message.
LED 6
LED 6 on the CPU is the ‘T&M-active-LED’. This LED turns on when the test and maintenance module
is activated. This is the case when tests are executed, error messages are received or the error
handling procedure is running, see paragraph
2.2. As soon as T&M is ready the LED is cleared.
Because T&M does not work in a continuous run, the LED often blinks.
3.6.3 LEDs on BS330 and BS340 type base stations
Power LED (LED 1)
The base station powered LED indicates whether the base station is powered.
LED 2
LED 2 is a three colour, software controlled LED. The different combinations are explained below.

) and DPANB 210 (DT368

Note1:
The cordless phone DPANB 204 (DT360) that is upgraded to GAP does not have the service display.
In service mode the cordless phone displays information regarding the radio interface like base station
number, carrier, time slot number, RSSI etc.
When the service display is active, calls cannot be made and incoming calls will terminate the service
display mode. To make this display visible while calling, first set-up the call and then, via the ‘R(inquiry)’
menu, access the service display menu.
