2-13. POWER CABLE. The transmitter is provided with a detachable line cord (8 feet

long) having a standard 15 ampere plug NEMA 5-15P (2 blades with round grounding

pin) at the supply end. Exposed portions of the equipments are grounded through

the round pin of the plug for safety. A non-grounded two blade receptacle should

not be used without use of a grounding-type connector adapter.

2-14. CABLES AND CONNECTORS

2-15. A list of cables used with the transmitter is given in table 2-1. Connectors used

are given in table 2-2. In addition, cable connections are illustrated in figure 2-5.

2-16. BATTERY INSTALLATION

2-17. Two different types of standby battery supplies are used in the TCS-4B. Some

transmitters have a non-rechargeable battery supply (P/N 6025-1008) that uses stand-

ard D-cell batteries. Other transmitters have a rechargeable supply (P/N 6025-1018)

that includes an integral charging circuit and uses sealed lead acid cells. Refer to

either paragraph 2-18 or 2-19 as applicable.

2-18. NON-RECHARGEABLE BATTERY SUPPLY (P/N 6025-1008). The standard

D-cell batteries may or may not be installed in the transmitter on arrival, depending

on shipping destination and enroute climate, etc. With new batteries installed, the

standby supply provides operating power for up to 24 hours (at 23C). To install bat-

teries, proceed as follows:

Loosen two captive thumbscrews at front of battery drawer on 1024 front panel.

Pull out battery drawer entirely.

Remove two screws at top of rear of container and slide battery cover out from

rear.

d. If existing batteries are being replaced, pry center front contact spring back

and remove center tube. Repeat for other two tubes.

e. Replace all batteries in + to - sequence and re-insert each tube according to

polarity markings on base of container.

2-19. RECHARGEABLE BATTERY SUPPLY (P/N 6025-1018). The rechargeable bat-

tery supply is installed for shipment in a drawer located in the front panel of the 1024

unit. Since the battery supply may have discharged during shipment, battery power

should not be relied on for the first 12 hours of operation. An internal charging cir-

cuit maintains a continuous charge on the battery supply when AC line power to the

1024 is on. After a 12 hour charge (with the 1024 turned on), the battery pack pro-

vides standby power for up to 24 hours (at 23C). Refer to paragraph 3-15 and 3-16

for additional information.
