USING AC POWER
You can operate the HTX-400 from AC power using a regulated power supply capable of supplying 13.8 VDC at least 1A and a vehicle power adapter (see “Using Vehicle Battery Power” on Page 12). The supply should also have an accessory power socket into which the DC-to-DC power adapter fits. If your power supply does not have an accessory power socket, you can either wire the power cord directly to your power supply or add an ac- cessory power socket to the supply. Suitable connectors, power supplies, power cords, and sockets are available at your local RadioShack store.
The following illustration shows how to connect a typical power supply, a DC-to-DC power adapter, and the HTX-400.
USING NI-CD OR NI-MH BATTERY POWER
You can use either Ni-Cd or Ni-MH batteries to power your HTX- 400; however, you cannot recharge these batteries while they are inside the HTX-400. You can use a separate external charger for recharging the batteries outside the radio. Your local RadioShack store carries a selection of suitable batteries and chargers.
Note: As these batteries provide less voltage than that typically supplied by alkaline batteries, expect less transmitting output power when you use the HTX-400 with Ni-Cd or Ni-MH battery power.
