a. Non-combat.
(1) Ensure locator beacon is operational.
(2) Follow standing plans for on/off operations to conserve battery use.
b. Combat.
(1) Turn off locator beacon.
(2) Keep it with you to supplement radio communications.
(3) Follow plans/orders for on/off operations.
c. Make initial contact as soon as possible or as directed in applicable plans/orders.
d. If no immediate contact, then as directed in applicable plans/orders.
e. Locate spare radio and batteries (keep warm and dry).
f. Transmissions.
(1) Use concealment sites (combat) that optimize line of site (LOS).
(2) Face recovery asset.
(3) Keep antenna perpendicular to intended receiver (Figure III-1).
(4) DO NOT ground antenna (that is finger on antenna or attaching bolt, space blanket, vegetation, etc.).
(5) Keep transmissions short (3-5 seconds maximum). Use data burst if available.
(6) Move after each transmission (ONLY in combat, if possible).
(7) If transmitting in the blind, ensure a clear LOS towards the equator.
(8) Use terrain masking to hinder enemy direction finding.
g. Listening (use reception times in applicable plans/orders or as directed by recovery forces).
