F

. If the H-1S9/GR Handset is being used, plug cable into connector un 377L-2 

Receiver-Transmitter Control.  Hook handset onto hook on right shoulder strap. 

G

. If headset is being used, place headset around operator's head with earphones 

over ears and metal connecting bar behind neck. Loop Velcro head strap over head 
and connect together. Loosen knurled knob and adjust microphone to a position 
directly in front of mouth; then tighten knob. Clip psah-to-talk switch (ptt) to 
clothing on chest. Plug cable into connector on 377L-2 Receiver – Transmitter 
Control 
 

Preliminary setup for stationary use 

 

A

. Lay assembled radio set on ground, either on its front or rear. 

B

. The radio set is normally operated with the standard whip antenna, which is 

generally satisfactory for distances up to 25 kilometres (15.5 miles). In dry or rocky 
terrain of low electrical conductivity, use the counterpoise with the whip antenna. 
Where greater distances are required, the dipole antenna should be used, and 
should be erected as close to the vertical as conditions allow. For considerably 
greater distances, the dipole should be erected horizontally between two supports, 
and its line should be at 90

0

 to the direction of the distant station. Select the desired 

antenna and install it as directed in preparation for use. 

C

. If the 540L-1 Battery Cable is being used, place the battery bag over the shoulder 

and strap it around the thigh of the operator, under the outer garments. 

D

. If the telegraph key is being used, strap the key to the thigh of the operator. Plug 

cable into connector on 377L-2 Receiver - Transmitter Control. Adjust key gap and 
tension as desired. 

E

. If the H-189/GH Handset is being used, plug cable into connector on 377L-2 

Receiver - Transmitter Control. 

F

. If headset is being used, place headset around operator's head with earphones 

over ears and metal connecting bar behind neck. Loop Velcro head strap overhead 
and connect together. Loosen knurled knob and adjust microphone to a position 
directly in front of mouth, then tighten knob. Clip push-to-talk switch (pit) to 
clothing on chest. Plug cable into connector on 377L-2 Receiver – Transmitter 
Control. 
 

886B-1 generator operation 

 
When the charge on a battery is too low to provide adequate power for receiver-
transmitter operation, a clicking sound will be heard on the headset or handset 
earpiece. The battery charge can be replenished in the field using the hand-crank 
generator. 
 
Recharging the battery can be accomplished with the receiver-transmitter turned 
off or while it is being operated. To recharge the battery, rotate the hand crank 
clockwise. Adequate charging current is generated when the green light on the 
hand-crank generator is lit. During normal operation, the red light should remain 
off.  In normal operation, the operator will not become prematurely fatigued.
