HOW TO CHANGED THE CERAMIC FILTERS

This model is used two ceramic filters of CF1 and CF3.
Y ou must use same type of color marked cer amic filters in order to
meet same specifications.
Therefore, the ceramic filter must be changed two pieces together
since it’s supply two pieces in one package as a spare parts.

Notes on chip component replacement

• Never reuse a disconnected chip component.

• Notice that the minus side of a tantalum capacitor may be dam­aged by heat.
