10. Maintenance
11A. Overview
While the Navigator 2.0 System is virtually maintenance-free, the user should follow a number of
steps to ensure proper performance prior to each use.
1.
Check each system component for any visible signs of abuse, neglect, or wear, before each
use and storage. This includes checking the following components and these features:
Table 11A-1. Component Check
Component Check Feature Check
Control Unit Overall check - Housing, integrity of switches and integrity
of connections.
Battery Charger Overall check - Housing and integrity of connections.
Probe (Wireless or cabled) Overall check. Also tip and connector.
Cable (if used) Each connector, the connector pins, and integrity of cable.
Gain Module (if used) Dial, cable and connector.
·
Should abnormalities be discovered, contact your sales representative or Dilon
Technologies directly.
·
Do not use a damaged control unit, battery, battery charger, probe, cable, or gain module.
2. Check each battery for function and charge before use. Should abnormalities be discovered,
contact your sales representative or customer support person.
3. To ensure proper functionality, follow each step as outlined in:
“Control unit, Battery, and Co-
Pilot,
” and the section in the manual pertaining to the relevant probe.
4. In addition to the above, preventive maintenance suggests that every two years a new battery,
fuse and cable (if used) might be considered.
5. User maintenance for the Wireless Pilot Probe is restricted to battery and battery cap
replacement. There are no user serviceable components or items on the Pilot Probe. Do not
attempt to repair damaged battery contacts, or any other damage to the probe.
WARNING!
No modification of this equipment is allowed. Any modification to this will void any
remaining warranty, if attempted.
11B. Verification of Standard Gain (Calibration Quick Test)
The Navigator 2.0 system is designed to minimize periodic maintenance, such that would be
performed by a clinical engineering department or the manufacturer. Depending on the probe used,
one of two procedures can be performed by the user.
11B-1. Verification of Standard Gain (Calibration Quick Test) - Background
For CABLED PROBES only.
Applies to the Standard Lymphatic Mapping Probes (SP-2A14-67 & SP-
2S14-67), Superficial Head & Neck Probe (SP-2S11-53), Laparoscopic Probes (SP-2S10-19 and SP-
2S10-31), and the Daniel
™ Lung Probe
(SP-2S10-31D)
.. Some institutions perform this Verification
of Standard Gain every six months or every year. The procedure does not calibrate the system; it
simply reveals whether or not the probe and control unit are set to a common gain standard
(calibration). That common standard relates the gamma photon energy detected by the probe to an
