Follow the instructions below for scanning for new frequencies and synchronising your transmitter and receiver in EW G2, EW G3 and EW G4 systems: 

To Perform an Easy Scan Setup: 

1. Turn on your receiver (please leave the transmitter turned off).
2. Hit the SET button on your receiver to enter the menus.
3. Use the arrows to find SQUELCH. Hit SET and adjust Squelch to LOW. Hit the SET button to store this setting.
4. Use the arrow buttons to scroll down to EASY SETUP. Hit SET which brings you into the Easy Setup menu.
5. Use the arrow keys to scroll down to SCAN NEW LIST. Hit the SET button to start the scan. You'll now see a progress bar on your screen as your receiver scans through all possible frequencies and looks for those with low background noise.
6. When the scan completes, hit SET two times to accept its recommended bank # and channel #. Your display will say “Stored.”
7. Turn on your mic or body pack transmitter unit and set it to the same bank # and channel # as your receiver by using the "Frequency presets" menu.
8. If you own "G3/G4" wireless equipment you could also create the link by holding your transmitter about 3 or 4 inches away from the face plate of your receiver and then hitting the "SYNC" button. If done correctly the receiver screen will show a check mark and the 2 units will then reflect the same bank, channel, and MHz numbers. The receiver will suddenly show full reception since it now detects your transmitter.
9. If you are in a challenging RF environment and your system reports 0 frequencies free, bump the Squelch setting back up to Medium and rescan.
10. If you have multiple systems to set up, then make sure that you select whatever "bank" had the most "free frequencies" available after completing your scan.
11. Most Sennheiser systems are sold in either the "A", "G", or "A1" frequency groups so if all of your systems are in the same band / group, then you will only need to perform a scan once and set all systems into the same bank but on different frequencies in that bank.
12. Let's say you have 2 systems in the "A" band, and then 2 more systems in the "G" band. You will need to perform a scan on one of the "A" units and then set both units onto the same open bank, while then performing a new scan for the "G" equipment and setting those 2 units into their own open bank.
13. Try to keep equipment of the same frequency "band" all in the same frequency "bank" for the best results. We have spaced out all of the frequencies inside each bank perfectly so that multiple systems won't interfere with each other.
14. It is ideal for you to perform a new scan whenever you change venues or locations, as each spot on the globe could have different RF conditions.

Check your new frequency:

• This check can only be performed before your transmitter (body pack or wireless mic) has been synched to your receiver. Once your transmitter has been synched properly, the RF meter on the receiver will be full to the top which indicates that you have a good connection between your mic/body pack and your receiving unit.
• If you have not yet synched your transmitter to your receiver, then you may briefly tap the ON/OFF button on your receiver. Tapping the ON/OFF will function as an "escape" and bring you back to the receiver's main display. If your unit says "Mute" and you see little to no RF on the meters, you've found a clean frequency on which to operate and may now proceed with synching your transmitter.

For Multiple Systems

• Use the FREQUENCY PRESET menu to set any additional systems into the same bank #, but to different channel #'s. The banks are sets of coordinated frequencies that we have calculated to work well together. All systems in the same frequency range should be operating in the same bank of preset frequencies to ensure the best performance.
• Keep in mind, background noise changes as you move to new locations, so always check your receiver before turning on the transmitter. You may need to perform a fresh scan at each new location, to make sure you're using the most reliable frequency for your wireless mics.
• Return the squelch setting to medium on all receivers once your scanning and setup is done.

You're all set!
