SERVICE SAFETY SUMMARY
FOR QUALIFIED SERVICE PERSONNEL ONLY
Refer also to the Operator’s Safety Summary.
DO NOT SERVICE ALONE
Do not perform internal service or adjustment of this product unless another person capable of rendering first aid
and resuscitation is present.
USE CARE WHEN SERVICING WITH POWER ON
Dangerous voltages exist at several points in this product. To avoid personal injury, do not touch exposed
connections and components while power is on. Disconnect power before removing protective panels, soldering,
or replacing components.
USE CAUTION WHEN SERVICING THE CRT
The CRT should be serviced only by qualified personnel familiar with CRT servicing procedures and precautions.
CRTs retain hazardous voltages for long periods of time after power-down. Before attempting any work inside the
monitor, discharge the CRT by shorting the anode to chassis ground. When discharging the CRT, connect the
discharge path to ground and then the anode.
Use extreme caution when handling the CRT. Rough handling may cause it to implode. Do not nick or scratch
the glass or subject it to undue pressure during removal or installation. When handling the CRT, wear safety
goggles and heavy gloves for protection.
REMOVE LOOSE OBJECTS
During disassembly or installation procedures, screws or other small objects may fall to the bottom of the
mainframe. To avoid shorting out the power supply, do not power up the instrument until such objects have been
removed.
LITHIUM BATTERY REPLACEMENT
To avoid personal injury, observe proper procedures for handling and disposal of lithium batteries. Improper
handling may cause fire, explosion, or severe burns. Don’t recharge, crush, disassemble, heat the battery above
212° F (100
°
C), incinerate, or expose contents of the battery to water. Dispose of battery in accordance with
local, state, and national regulations.
