The B737NG SELCAL reproduces the analogous panel present on the 737NG pedestal.
The functions of the pushbuttons and leds on the B737NG SELCAL depend on the connected software.
The B737NG SELCAL panel is connected to the brightness regulation panel (B737NG BRIGHT PANEL) through a single flat cable (integrated), so it requires B737NG BRIGHT PANEL panel to function.

SELCAL737 disposes of:

– 5 warning pushbuttons: VHF1, VHF2, VHF3, HF1 and HF2.
– 5 warm white annunciators
– 1 flat cable (integrated) to connect SELCAL panel to the B737NG BRIGHT PANEL.
