Safety Instructions, Warnings and Notes

2.1. Safety Instructions
2.1.1. Safety components
Replace safety components, indicated by the symbol
substitution (other than original type) may increase risk of fire or electrical shock hazard.
2.1.2. After repair
•
Safety regulations require that after a repair, the set must be returned in its original condition.
•
Before returning the MCP9360i to the customer always do a safety check. Pay attention to the built-in protective devices, leakage
current and insulation resistance.
2.2. Warnings
2.2.1. General
Never replace modules or other components while the unit is switched "on".
2.2.2. ESD Protection
All ICs and many other semi-conductors are susceptible to electrostatic discharges (ESD). Careless handling during
repair can reduce life drastically. When repairing, make sure that you are connected with the same potential as the
mass of the set via a wrist wrap with resistance. Keep components and tools also at this potential.
2.3. Notes
2.3.1. Schematic notes
•
All resistor values are in ohms, and the value multiplier is often used to indicate the decimal point location (e.g. 2K2 indicates
2.2 kohm).
•
Resistor values with no multiplier may be indicated with either an "E" or an "R" (e.g. 220E or 220R indicates 220 ohm).
•
All capacitor values are given in micro-farads (µ = x10
•
Capacitor values may also use the value multiplier as the decimal point indication (e.g. 2p2 indicates 2.2 pF).
•
An "asterisk" (*) indicates component usage varies. Refer to the diversity tables for the correct values.
•
The correct component values are listed in the Spare Parts List. Therefore, always check this list when there is any doubt.
