6.4 Replacement of Radiation Source Lamp
This lamp is warranted for 1 year. The user must not attempt to
replace the lamp definitely. Entrust lamp replacement work to a
service engineer who has received training at Hitachi High-
Technologies.
6.5 Caution on Lithium Battery
CAUTION
The Model U-5100 ratio beam spectrophotometer uses a
lithium battery for memory backup. If the lithium battery is
handled in a wrong way, it might burst.
Never try its recharging, disassembly and throwing into a
flame. This battery must be disposed by a different
method from that of general wastes.
When replacement of the lithium battery becomes
necessary (for example, an error message “RAM Check
NG” is frequently issued), contact your dealer or the
maintenance service company authorized by Hitachi High-
Technologies.
Entrust this replacement work to a service engineer who
has received training at Hitachi High-Technologies (you are
charged for this work after the warranty period of the
instrument).
