2. Gain access to the rear of the monitor.
3. Gently pull the old card out of its socket and slide it out of its card guide.
4. Plug the replacement analyzer card into the guide.
N O T E : The components of the analyzer card face left when the card is installed correctly.
5. Plug in or turn on all incoming power to the monitor at the power source end., then verify that the
pilot light on the replacement analyzer card is flashing.
CAUTION: If installing a new channel, define the channel
position as Oxygen and activate (see detection
insert) before turning power off to plug in new
module.
Replacing the AC Fuse
1. Turn off or unplug all incoming power to the monitor at the power source end.
2. Gain access to the rear of the monitor.
3. Gently pull the Power I/O card toward you and slide it out of its plastic card guides.
4. Remove the AC fuse(s) from its holder. The AC fuse(s) is behind the AC terminal strip and to the
right of the relays.
N O T E : If the monitor is configured for 115 VAC operation, only one fuse is used, F1. If it is
configured for 220 VAC, both F1 and F2 are used.
