Laser Enable Mode
The Laser Enable Mode parameter indicates
whether the LS 3020 must establish communi-
cation with the Motorola terminal prior to at-
tempting a decode. If this parameter is
enabled, the following sequence occurs when
the trigger is pulled:
• The scanner sends an ENQ (05H) to
the terminal.
• ThedecodeLEDflashestoindicatethe
scanner is waiting for acknowledg-
ment from the terminal. The LED
stops flashing when ACK (06H) or
NAK (15H) is received, or the trigger
is released.
• If an ACK is received, the unit at-
tempts a decode.
• If a NAK is received, the unit issues
four short low beeps.

Aiming LEDs andTrigger Posi-
tions
The LS 3020-I037A does not generate an aim-
ing LED.
An aiming LED is provided for the
LS 3020LR-I037 or LS 3020ALR-H037 when
the trigger is pulled. These scanners support
a two-position trigger to allow the user to aim
prior to activating the motor.
Whenthetriggerispulledinthefirstposition,
the aiming LED is generated. If the trigger is
not pulled to the second position, the aiming
LED turns off after approximately two sec-
onds.
Triggering and Laser Enable
Mode
If the Laser Enable Mode is disabled, the scan-
ning motor is activated as soon as the trigger
is pulled to the second position.
If Laser Enable Mode is enabled and the trig-
ger is not pulled to the second position, the
aiming LED remains on for two seconds, and
the unit does not transmit an ENQ. If the trig-
ger is pulled to the second position, the unit
transmits the ENQ to the terminal.
• If an ACK is received, the unit at-
tempts a decode.
• If a NAK is received, the aiming LED
is turned off, and the unit issues four
short low beeps.
• If the unit does not receive anACK or
NAK, the aiming LED remains on for
two seconds. The decode LED contin-
ues to flash until anACK or NAK is re-
ceived.
