4. ESD Protection Specification
Tuner will be packed with anti - static poly foam to prevent the ESD
damage. Do not touch the tuner pins before grounding yourself. Anyone
handling the tuner must wear a properly grounded anti - static discharge
bracelet.

4-1. RF Connector
Test is performed with a voltage discharge from a 150pF capacitor over
a 330Ω series resistance in the discharge path. There is a direct contact
between the test probe head and the RF connector with ± 8 KVDC.
4-2. Module Pins
Test is performed with a voltage discharge from a 150pF capacitor over
a 330Ω series resistance in the discharge path. There is a direct contact
between the test probe head and pin 1 through 11 with 3 successive ESD
discharges of ± 2 KVDC.
