Alerts
The control panel displays various alerts to the user in the form of Acknowledged Alerts, Unacknowledged
Alerts, and Error Alerts. An Acknowledged Alert displays over the printer status icons and requires user
input to be cleared, i.e. press the Select button to clear such an alert.

An Unacknowledged Alert also displays over the printer status icons, but in this case it does not require
user input to be cleared. The alert will automatically be cleared after being displayed for five seconds.
Error Alerts also appear over the printer status icons and require no user input via the front panel to be
cleared, but they do require the user clearing the error condition by other means. The Error Alert will
remain on the display until the error condition is cleared.
Power Saving Features
The printers have a few key features designed to extend the life of the battery. These features are
described below.
Sleep Mode
The Sleep Mode feature is a way the printer conserves battery life whereby the printer will automatically go
into a “sleep” state after two minutes of inactivity. When the printer is in this state there will be no content
displayed on the LCD in addition to no backlight. The printer will indicate Sleep Mode by a slow blinking
green LED ring around the Power Button (see LEDs on page 30).
• If the Power Button is pressed for less than three seconds (<3), then the printer will enter Sleep Mode.
• If the Power Button is pressed for more than three seconds (>3), then the printer will power down
completely.
In order to “wake up” the printer, the user must press the Power or Select <icon> buttons for less than
three seconds, or the printer will wake up on its own when communication is initiated via Bluetooth.
NOTE: Wake On Bluetooth is only supported in BT 4.1 radio, not in the Dual Radio unit.
The printers will also wake from Sleep Mode when communication is initiated via WLAN. If the Power
Button is pressed for more than three seconds, the printer will wake up and shut down completely.
To enable or disable Sleep Mode, send the power.sleep.enable command to the printer using Zebra Setup
Utilities (ZSU) and set it to either
"on" or "off". (The default setting is “on”.) To set the time after which the
printer will enter Sleep Mode, send the power.sleep.timeout (in seconds) to the printer using the ZSU.
