outward. If the connectors are properly mated, 
a slight resistance will be felt. 
NOTES: 
1. Do not adjust trimmer capacitor C4. The 
capacitor is factory-calibrated. 
2. When transporting the PCTU, keep the P7 
battery strap in the ON position if it is de- 
sired to save the configuration data stored 
in PCTU RAM (the battery will protect 
RAM for approximately six years); other- 
wise, to conserve the lithium battery, move 
P7 to the OFF position....
