Install a 9-volt alkaline battery (Eveready 522 or equivalent, not supplied). Observe the battery polarity (+ and -). Replace the battery cover. (Rechargeable batteries are not recommended because the 74-200 will not charge the battery.)

INITIAL SETUP

Connecting power –

The AC power adapter is required for normal operation if the radio is to be in service for more than a few hours. Plug the wall adapter into a 110-115 Volt AC (standard house current) outlet. Connect the cord end to the DC-12Volt power jack on the back of the unit.

A backup battery as stated above is also recommended. The condition of the battery is monitored by the radio. When REPLACE BATTTERY appears on the display, the battery has been discharged and should be replaced. Do not leave a dead or weak battery in the radio. Do not leave a battery in the radio when it is not in use. The battery may leak and possibly damage

your unit. Dispose of batteries properly.

Antenna -

The telescoping antenna on the back of the radio should be positioned vertically and extended to its full length. In most cases this antenna should provide good reception of your NWR broadcast.

In some cases especially in remote areas an external antenna may be used to improve weak reception.
