1.  On/Off & Volume Control

 This knob functions as the power 

on/off switch and controls the audio output volume. 
 

2.  Tuning Knob

 

 

NORMAL MODE: 

Turning the Tuning Knob changes the fre-

quency of the receiver. The tuning rate varies with the speed at 
which the knob is turned. There are two tuning rate ranges. The 
SLOW rate is 20 Hz per step, increasing to a maximum of 100 Hz 
per step as the knob is turned faster. The FAST rate is 100 Hz per 
step, increasing to a maximum of 500 Hz per step as the knob is 
turned faster. To switch between the two rates, press the Tuning 
Knob toward the front panel until it clicks. To return to the other 
rate, once again press the knob until it clicks. With a bit of experi-
ence, you can easily tell which rate is selected by watching the 
digital display change while turning the knob. 
 

MEMORY MODE: 

Once Memory Mode is enabled (by pressing 

the MEM button once), turning the Tuning Knob steps through the 
stored memory channels. Pressing the Tuning Knob toward the 
front panel until it clicks switches between display of the channel 
numbers and display of the frequency of the stations stored in 
each memory channel. 
 
If the digital display shows “CH” {number}”, [{number} is the num-
ber of the active memory channel]; then pressing the Tuning Knob

building, it may be too shielded for an indoor antenna to work well. 
 
Performance of the antenna will be improved by providing an earth 
connection to a ground stake. For best results, get a good quality 
ground stake approved for grounding an electrical service en-
trance, and drive it at least 8 feet into the earth. The wire from the 
ground rod connects to the wing nut or to the Black terminal on the 
antenna connector block on the back of the radio. The wire used in 
an outdoor antenna needs to be strong enough to support its own 
weight, as well as to hold up any additional weight such as ice 
from an ice storm. Normally, 14 gauge or larger is considered an 
adequate size, especially if the wire is copper-clad steel especially 
designed for antenna use. If the far end of the antenna is sup-
ported by a tree or other support that sways in the wind, a pulley 
and weight arrangement will prevent the swaying from putting ad-
ditional strain on the wire. 
 

 

WARNING: Any outdoor antenna MUST be located 
so that it cannot fall on power lines or power lines 
cannot fall on it, if they should come down.  Also, 
any outdoor antenna MUST have an approved 
lightning arrestor, installed in accordance with ap-
plicable building and electrical codes, at the point 
where the antenna connection enters the building.
