Battery Maintenance
Due to the self-discharge characteristics of this type of battery, it is imperative that it is
charged after 6 to 9 months of storage (or unit not in use). If not, permanent loss of capacity
may occur as a result of sulfation. Charge retention at 20
o
C is 6 months to 83%.
The batteries used in the Passport XG Monitor are of sealed lead acid construction. This
battery type may be subject to local regulations regarding disposal. At the end of the battery
life, dispose of the batteries in accordance with any local regulations.
8.6.8 Recorder Paper Replacement
The instructions below describe the replacement of recorder paper. Use only recommended
recorder paper, P/N 0083-00-0422. This ensures that the print quality is acceptable and
reduces print head wear.
1. Open recorder door by pressing the paper eject button (upper right corner with paper
roll icon on it).
NOTE: If the recorder’s door does not open completely, carefully
pull it until it is completely open.
2. Remove empty paper spool by pulling it out gently.
3. Insert new paper roll between the two rounded tabs of the paper holder with the
sensitive (shiny) side of the paper facing the print head at the top of the recorder (paper
feeding off of the spool from the bottom).
4. Unroll approximately 4 inches of paper.
5. Align the paper across the top of the metal bar.
6. Holding the paper in place, close recorder door.
7. To ensure that the paper is aligned properly and has not been pinched in the door, pull
the loose edge out a couple of inches. If the paper jams, open the door and return to
step 5.
8.6.9 Care and Storage of Thermal Chart Paper
Thermal Chart Paper is chemically treated and the permanency of a recording is affected by
storage and handling conditions. These conditions are:
• Ultraviolet Light
We recommend storing the recordings in a filing cabinet within a few days of printing. Long
term exposure to natural or artificial U.V. sources may be detrimental.
