Figure 4d: Attaching the Video Viewer to its charger
When charging, the LED light indicator on the Video Viewer illuminates to display
the charge status as follows:
RED
Battery is charging.
RED up to 2 hours
later
RED LED should switch off, indicating that the battery is now
fully charged and the Video Viewer may be removed for use.
During normal use, the LED light indicator on the Video Viewer illuminates to
display the battery status as follows:
GREEN
ON and the Video Viewer is operating correctly.
GREEN steady
flashing
ON but battery has low charge. Proceed to charge the Video
Viewer prior to use.
No light
OFF or the battery is exhausted. Proceed to charge the Video
Viewer prior to use.
The GREEN light indicator only ever operates if the video laryngoscope is switched
ON or if the TEST button on the Video Viewer is pressed. It cannot be controlled by
the Video Viewer Charger.
The TEST button should not be used while the Video Viewer is connected to the
charger as the GREEN light indicator may give an incorrect charge indication in
this situation.
CAUTION
: Before any procedure, the Video Viewer must be checked to ensure that it
is operating correctly and the battery level is sufficient. If the LED light indicator starts
to flash during a procedure it means that there is limited battery. The procedure
may continue at the clinician’s discretion.
The Camera Module is supplied with an alkaline AA 1.5V battery. When used as a
standard laryngoscope, the Camera Module illuminates when the device locks in the
‘ON’ position. The battery should be replaced regularly with an alkaline or lithium
AA 1.5V battery to prevent the laryngoscope from failing suddenly without warning.
To replace the single AA 1.5V battery in the Handle, first remove its front cover which is
the side furthest away from the notch (
Figure 4.1a
). Slide the cover in the direction away
from the connector cap (
Figure 4.1b
). An audible “click” may be heard as the cover
disengages from its locked position (
Figure 4.1c
). Lift the cover away from the Handle
to reveal the inner battery cover (
Figure 4.1d
). Remove the inner battery cover and the
attached battery ribbon will allow the fitted battery (if one is present) to be removed
and replaced (
Figure 4.1e
). Ensure that the ribbon is placed beneath the new battery
and check that the polarity of the battery cell is aligned correctly to the markings on
the Handle (
Figure 4.1f
). Once this is done, replace the battery cover and slide the
cover back onto the Handle. If the laryngoscope is to be stored, e.g. not to be used
for some time, the battery should be removed.
