Battery Charging and Care

To ensure peak performance from your radio, the battery pack must
be fully charged. Proper care and charging will allow maximum
performance and life of your battery pack.

The SA-1120 Pedestal Charger, available optionally for your SL-70W
Series Radio, offers convenient charging capabilities. The charging
cycle with this charger is overnight (12-16 hours). For longest
battery life try to avoid charging the radio for more than 24 hours
at a time.

The optional SA-1125 Desktop Quick Charger provides "one hour"
charging and normal "slow" charging to two units simultaneously.
The high capacity 1200 mAh battery pack will take longer to fully
charge.

See accompanying instructions included with these chargers for
more information.

To receive maximum performance from your radio and battery
pack, periodically completely discharge and recharge the battery
pack.

SL-70W Series Operations

Power On-Volume

Turn the radio on by rotating the on/off - volume control clockwise
until you hear a click and the self test "alert" tone.

Transmit

OPERATION OF THE TRANSMITTER WITHOUT

A PROPER ANTENNA INSTALLED MAY RESULT IN

PERMANENT DAMAGE TO THE RADIO

1) Press the monitor button to monitor the channel for activity. To

avoid interrupting another user, make sure the channel is clear

before you begin transmitting.

NOTE: Federal Communications Commission Rules and Regulations
require that you monitor a channel for activity before transmitting.

NOTE: The tri-color LED located on the top panel can help with
channel monitoring. It will glow amber if RF activity is present; or
green if the transmission has a CTCSS or DCS tone that matches a
tone programmed for receive in your radio. When this LED is not
illuminated, the radio is indicating a "clear" channel.

2) When the channel is clear, hold the radio upright with the

antenna vertical and the front grille area about 2- 3 inches from
the mouth, keeping the antenna away from the face and eyes. Press
and hold the P-T-T bar on the side of the radio, and speak slowly
and clearly into the grille area.

NOTE: The LED will glow red when transmitting. This indicator
should be on continuously while the P-T-T bar is being pressed and
the radio is transmitting. Should the red LED be "flashing", the
battery needs to be recharged and transmission will cease. Recharge
the battery before attempting more than one transmission.

Receive

When you have finished transmitting, release the P-T-T to receive.

CAUTION

9

Power Off

When finished transmitting, receiving, monitoring, etc., turn the
radio off by rotating the on/off- volume control fully counter­clockwise, to the detent position.

Status Indicators and Audible Alert Tones

Your SL-70W Series has a sophisticated microprocessor control which
provides a series of audible alert tones.

Upon initial power up, a quick melody indicates that the self-test of
the microprocessor functions has been completed satisfactorily. A
series of tones may be sounded with any of the following conditions:

• Attempt to transmit on a channel set for receive only

• Attempt to transmit on a channel that is already in use when busy

channel lockout has been programmed into the radio *

• Transmitting time has exceeded time-out timer programmed length

*

• Low battery condition

• Selecting a channel with no programmed frequency

* Indicates a function that is initially programmed into the radio by

your Maxon Dealer.

NOTE: All audible tones can be programmed off for silent
operation.

Scan Modes

Scanning is a Dealer programmable feature that allows you to
monitor a number of channels. Your Dealer will help you define a
channel "scan list" to be programmed into a scan channel (any
channel, 1-16). Once that channel location is selected, scan is
initiated.

Normal Channel Scan

Once the scan list is programmed you can initiate scan. Simply
move the channel selector knob to the scan channel position
and the radio will start to scan. The top panel LED can be
programmed to flash green as the radio is scanning.

If a conversation is detected on any of the channels in the scan
list, the radio will stop on that channel and you will be able to
hear the conversation. If programmed for normal scan TX you
will be able to transmit on that active channel during the
programmable scan delay time. The scan delay time is the
amount of time the radio will stay on that channel once activity
has ceased (Dealer programmable, 4-7 seconds is typical). The
radio will resume scanning once the scan delay time has
expired. Scanning will continue until the channel is changed.

Priority Channel Scan

A single channel may be programmed as the "Priority" channel.
The radio will constantly monitor this channel while scanning
and when the radio has stopped on an active channel. If a call
is detected on the "Priority" channel, the radio will automati­cally move to, and remain on, the "Priority" channel for as long
as the priority conversation takes place. "Priority" channel
activity takes precedence over all other conversations.

NOTE: "Priority" channel scan and "look back" require that the
radio leave the active channel for a fraction of a second (at
regular intervals) to check the priority channel for a message.
Depending upon how the radio is programmed (scan speed,
etc.) this may or may not be noticeable as "breaks" on the
active channel for that same fraction of a second.

11

Other Scanning Features

• Look Back: Any channel, when not in the scan mode, can be

programmed to "look back" at the "Priority" channel. This
feature is ideal for those who do not need scan as defined above,
but want to make sure that they never miss a call on the "Priority"
channel if another channel has been selected. Once a "look back"
channel has been selected, the radio will periodically "look back"
at the "Priority" channel. If activity is detected on the "Priority"
channel, the radio will move to that channel for as long as it
remains active.

• Scan Channel Delete: To temporarily delete a channel from the

scan list, simply press the monitor button while scanning and
stopped on the channel to be deleted. This will remove that
channel from the scan list until the channel is changed or the
radio's power is reset. When power is restored or the scan list
channel position is again selected, the original Dealer pro­grammed scan list will be activated.

• CTCSS/DCS Scanning: The SL-70W can be programmed by your

Dealer to scan for tone. This will help block out unwanted calls.

• Normal Scan TX: Allows a transmission only after a call is

received, depending on the programmed scan delay time. After
the scan resumes, and a transmission is made, the radio will sound
an alarm (two beeps) and will not allow a transmission.

• Priority Scan TX: Allows a transmission after a call is received

depending on programmed scan delay time. The transmission will
be made on the channel that the call was received. After the scan
resumes, if a transmission is made, the radio will transmit on the
programmed priority channel.

• Priority Only TX: Allows a transmission on the priority channel

when scanning and not stopped on an active channel. It can also
be programmed to always transmit on the priority channel if
scanning or stopped on an active channel.

• Receive Only Scan: This allows only reception. If a transmission

is made at any time, the radio will sound an alarm (two beeps) and
will not allow the transmission.
