Ni-Cd BATTERY PACK (PB-2)
NOTE:
This battery pack has not been charged at the factory in order to pro-
vide you with the greatest number of charge/discharge cycles. You
must charge the battery before use. The battery pack will require
several charge/discharge cycles before you can expect to see the
maximum operating period between charges. If the battery will be
stored for greater than 2 months it should be recharged before use.
Battery release button
Battery pack
RECHARGING THE BATTERY PACK
Insert the charge plug from the BC-2 into the receptacle on the
rear of the battery pack. Then plug the BC-2 into the AC line.
The LED on the BC-2 will illuminate to show that the pack is
charging. The LED will remain on as long as the BC-2 is con-
nected to the AC power source and the battery, indicating
that the pack is still being charged. Do not allow the battery to
charge for greater than 15 hours. The useful life and battery
performance will be reduced if you exceed the recommended
charge period.
NOTES:
Turn off the power switch before charging.
° Recharging should be done within an ambient temperature bet-
ween 10°C ~40°C (50°F~104°F). Recharging performed out
of this range may not fully charge the battery.
MANGANESE or ALKALINE BATTERIES
Load 6 x R6 (AA) manganese or
alkaline batteries in series in the
supplied battery case. (Be sure to
observe the polarities.)
(We recommend use of high-
perfomance manganese batteries.)
Battery pack (1) can be inserted in-
to the case (2) only in a specific
direction. Check the shape (top and
bottom) after moving the stopper case (2)
on the rear side, then insert the bat-
tery correctly. Inserting the battery
by force without checking the
shape may damage the case.

After power and antenna connections have been com-
pleted, set the switches as follows:
1. Turn the VOL control clockwise to turn on power. The
frequency on the LCD display will show the transceiver
is operating.
2. As the VOL control is turned clockwise, either
background noise or a QSO will be heard.
3. To eliminate the no-signal noise turn the SQL control
clockwise.
4. Enter the desired frequency.
@ TRANSMIT
Precaution: Check the intended transmit frequency before
operating to prevent interference with other
stations. If you are using T. SQ (Tone
Squelch) press the MONITOR key to allow the
Squelch to open.
1. Simply depress the PTT switch and the [ON AIR] in-
dicator will light.
2. Speak into the microphone. Recommended distance to
the microphone is approximately 2 inches (5 cm).
CAUTION:

HREPEATER OPERATION
@ Transmitter offsets
All amateur radio repeaters utilize a separate receiver and
transmitter section. The receiver frequency may be either
above or below the transmitter frequency. The transceiver
allows you to store the frequency and offset in memory, or
you can select the offset and offset frequency from the
keyboard.
Offset direction
To select the desired offset, press the OFFSET/F key. Each
time you press the key the radio will advance from one off-
set to the other, i.e. ‘’+’’ to ‘‘—"’ to no offset or simplex.
Offset frequency selection
To select the desired offset frequency, press the [F_] and
the OFFSET/F key. The display shows present transmitte
offset.
Press either the [4 _] key or the [¥_] key momentarily,
the frequency change 100 kHz step up or down from lower
limit 100 kHz to upper limit 9.9 MHz. Press the [ENTER]
key to complete the selection.
NOTE:
You can enter any offset you desire, but if you select an
offset that would cause the radio to go out of band the
radio will ignore the programmed offset, and transmit in the
simplex mode. (For MARS and CAP operators who have
modified their radios to cover the MARS and CAP frequen-
cies this may not be the case. For these sets the
transceiver will accept any offset that does not take it out-
side its tuning range. See the instructions supplied with the
MARS/CAP modification sheet.)
12
® Reverse function .
Some repeaters utilize a ‘‘reverse pair’’, i.e. the transmit/
receive frequencies are exactly the reverse of another
repeater. For example repeater A uses 146.000 for a transmit
frequency (OUTPUT) and 146.600 for receive (INPUT).
Repeater B uses 146.000 for its receive and 146.600 for its
transmit. It would be inconvenient to have to reprogram the
radio each time if you were in range of both repeaters.
The R/TONE. F key has been provided to allow you to reverse
the transmit and receive frequencies.
TH-415E/215E: Transmission is inhibited when the
REVERSE key is engaged.
To use the REVERSE function, press the R/TONE. F (or press
and hold the REVERSE) key. The R indicator will light in the
display.
To return to normal offsets press the R/TONE. F (or release
the REVERSE) key again. This function is useful to check the
input frequency of the repeater so that you can determine if
you are within SIMPLEX range.
@ Tone operations
Some repeaters require the use of a control signal to activate
the repeater. Several versions are currently in use worldwide.
TH-415A/315A/215A:
These transceiver provides a subaudible tone encoder with 38
standard tone frequencies. To activate the appropriate tone
signaling device, depress the TONE switch on the top of the
radio.
The decoder section is an optional accessory (TSU-4). That
allows for T.SQ (Tone Squelch) operation. With this option
you will only hear those stations that transmit the same
subaudible tone directly.

TH-415E/215E:
In Europe a 1750 Hz tone is used in transmit. In the United
Kingdom a 1750 Hz tone burst at the beginning of each
transmission is used. Since use of these tones is required in
the U.K. and in Europe the tone encoder is included as stan-
dard equipment.
Tone frequency selection
To select the tone frequency, Tone Frequency
press the |F | and the 67.0 Hz | 107.2 Hz | 167.9 Hz

Tone Squelch operation
To actuate the tone squelch function (decode), turn the
Squelch control fully counterclockwise past the detent.
Squelch will now open only when the radio receives the
same subtone frequency. To return to normal noise ac-
tivated squelch, turn the Squelch control clockwise past
the detent.
It is a good operating practice to check the frequency
before transmitting. A MONITOR switch has been provided
for this purpose when using the TONE SQUELCH function.
Pressing this switch will open the squelch so you can check
for activity.
NOTE:
97.4 Hz is available only for encode.
