2. Conditions
SuppJy Voltage : 110 V 60 Hz
Unless otherwise specified, S551, 552, 553 and 554 shall be switched
OFF.
3. Procedure
STEP ITEMS TO BE CHECKED
1 Rotate CH rotary switch and check if CH LED's in ail channels from
CHI - CH40 are correctly displayed. Furtherraore, check if there
are no notable différences in luminance.
2 When S554 is switched "ON", check that "19" is displayed on CH LED.
3 Check that me ter lamp, PL551 and 552 are always turned ON.
Likewise, there should be no notable différence in luminance.
4Check that TX LED and RX LED are properly lit. When the jig's PTT
is ON, the TX LED should be ON and the RX and jig's PA LEDs should
be OFF. When the jig's PTT is OFF, the TX, RX and PA LED indicators
output will be reverse.
5When S551 is switched ON, check that the jig*s NB/ANL LED turns ON.
6When S553 is switched ON, check that the jig*s hi—eut LED turns OFF.
