Coast HP4 User Manual
Turn the end cap in a counter-clockwise direction to remove the cap.
Place two AAA batteries into the light, positive end of the battery first.
Replace the tail cap and turn it clockwise to tighten it until it is fully closed.
The HP4 has a rear switch on the tail cap.
To turn on the light, press the switch fully until it “clicks.”
To turn off the light, press the switch fully until it “clicks.”
The light can also be operated in “momentary” mode. Momentary mode is activated by
partially depressing the on/off switch (less pressure than required for a full click).
