Making the call by speakerphone：After the phone is placed off-hook, dial and use “#” key as the end dialing symbol. 2. Hold Key You can keep and release the call of current line. The only one line is presently in a call, the other line must be placed on hold. 1) Place the call of one line on hold Make sure that the call you want to keep is enabled, then press " Hold" key. 2) Release Hold Make sure that the call is initiated, then press "Hold" key. 3. Volume Control Press “VOL▲” to increase the volume, while press “VOL▼” to decrease the volume. 4. Mute During the call, if you do not want to let them hear your own voice, you can press "Mute" key, so that the other party cannot hear your voice, and you can hear the sound of other end. 5. Memory Key In addition to serving as a storage function, but also can be used as hold, DND, transfer and conference function. See the web call feature function set. 6. Tripartite Conference Function If the phone is Line1 hold, line2 in the call, press the conference key, which can achieve three party conference. During the three party conference, the base unit and handset cannot be switched each other. 7. Transfer The telephone is in conversation with A, A wants to call B, you can press the Transfer key, and then call B, press the T ransfer button again after B hooking off, the transfer function can be achieved. 8. Call Park After the call park feature is enabled, and Hold Key Active and Idle Hold Key related parameters are configured, we can perform the function of park.

The MPE-based test exemption condition is in terms of ERP, defined as the product of the maximum antenna gain and the delivered maximum time-averaged power. For this case, a RF source is an RF exempt device if its ERP (watts) is no more than a frequency-dependent value, as detailed tabular form in Appendix B. These limits have been derived based on the basic specifications on Maximum Permissible Exposure (MPE) considered for the FCC rules in § 1.1310(e)(1). Table to § 1.1307(b)(3)(i)(C) - Single RF Sources Subject to Routine Environmental Evaluation f = frequency in MHz; R = minimum separation distance from the body of a nearby person (appropriate units, e.g., m); For multiple RF sources: Multiple RF sources are exempt if: in the case of fixed RF sources operating in the same time-averaging period, or of multiple mobile or portable RF sources within a device operating in the same time averaging period, if the sum of the fractional contributions to the applicable thresholds is less than or equal to 1 as indicated in the following equation: Bay Area Compliance Laboratories Corp.
