tries to match with the DL by the UL Gain Offset value. If the UL Gain Tracking is OFF, the

DL and UL will work individually. (If ALC On, UL Gain Tracking is On automatically. UL

Tracking On/Off function is inactive, Basic Gain deviation of DL and UL is -10dB at MHU)

⑤ ASD(Automatic Shut Down): MHU exists UL ASD only. If UL Output Power maintains for 3

seconds(ASD Time) at the ASD Level, it occurs Shutdown. If Shutdown is repeated 5

times(ASD Count), Easy Max Setup is needed.

⑥ Return To Factory default: Initialize function

⑦ Easy Max Setup: If Easy Max Setup executes, execute after all linked systems initializing.

Complete EHU and RU ID setting before executing Easy Max Setup.

Execute Easy Max setup after checking Link status of each unit is normal.

* MHU-EHU-RU Link

MHU: DL/UL Path On Æ DL ALC On (ALC Level 5dBm), UL Gain Tracking On (UL Gain

Offset -10dB)

EHU: CLC On(Output 5dBm) Æ Operating CLC from the Min Gain

(UL Gain is linked to DL Gain)

RU: RU CLC On (iDEN -27dBm/CDMA -41dBm) Æ DL/UL Path On Æ DL ALC On(20dBm),

UL Gain Tracking On(UL Gain Offset 10dB) Æ DL ASD On(ASD Level 23dBm)

* MHU-RU Link

MHU: DL/UL Path On Æ DL ALC On (ALC Level 5dBm), UL Gain Tracking On (UL Gain

Offset -10dB) Æ UL ASD On

RU: RU CLC On (iDEN -31dBm/ CDMA -37dBm) Æ DL/UL Path On Æ DL ALC On (ALC

Level 20dBm), UL Gain Tracking On (UL Gain Offset 10dB) Æ DL ASD On

⑧ Band Status: iDEN 800MHz bandwidth can select band as 18MHz and 7MHz. 900MHz

bandwidth is fixed to 5MHz.

iDEN 800MHz band can be select at 18MHz and 7MHz, 900MHz band fixed at 5MHz

⑨ Alarm Status: It shows alarm status of MHU. If it is out of Normal Range, Alarm is occurred.

ASD is also occurred if it is shutdown.
