387 Feature: Sleep - k3ng/k3ng_cw_keyer GitHub Wiki
Sleep Mode
Sleep mode will put the unit into a sleep state after a certain period of inactivity. This is done in order to preserve battery power. To enable the feature, uncomment this line:
#define FEATURE_SLEEP
The inactivity timer is set here (the unit is minutes):
#define go_to_sleep_inactivity_time 10
To wake the keyer after it goes to sleep, simply hit the left (normally dit) paddle.
