This article answers some of the popular questions about the features and functionality of the Job Rocker Max.





My Job Rocker Max is not charging. What should I do?

This symptom could be caused by a burned out fuse. To determine if a burned out fuse is the potential cause of your battery not charging, connect the Job Rocker Max to a power source and look at the level meters on the back of the Job Rocker Max.

If the charging light is lit, this indicates that the Job Rocker Max is currently charging and the fuse is not burnt out. However, if the battery is fully charged, the charging light will not be illuminated.

If the battery level lights are less than completely full and the charging light is not illuminated while the Job Rocker Max is connected to a power source, then the fuse has more than likely burned out. The steps below will walk through replacing the burnt out fuse.

  1. Disconnect the Job Rocker Max from any power sources and completely remove the power adapter (IEC cable) from the unit.
  2. Locate the fuse door next to the IEC power cable port on the rear of the Job Rocker Max.

  3. Carefully open the fuse door using a flat-head screwdriver.

  4. Inspect the fuse to see if it has burned out.

    All other regions - 315mA/250V

  6. If the fuse has not burned out, the battery may need to be replaced. Please refer to the following article:

What is Easy Pairing? What is NFC (Near-Field Communication)?

Easy Pair is a form of NFC tap pairing, otherwise known as 'bump pairing'. NFC stands for Near-field Communication and is the power behind the technology used in the ION Audio Job Rocker Max. More information on Near-field Communication can be found here and here.

Basically, NFC allows a device, usually a mobile phone, to collect data from another device or NFC tag when it is moved into a close range. In many ways, it’s like a contactless payment card that is integrated into a phone. In other ways, it’s similar to Bluetooth, except that instead of programming two devices to work together, they can simply touch to establish a connection.


Is my device NFC enabled?

Many popular Android smartphones have this feature. To date, there is no iOS device that is NFC enabled. You may need to refer to your device information, manual, or support to determine if your device is NFC-capable, however, the link below may help:


I get feedback when I use a microphone. How can I prevent this?

There are a few easy steps you can take that can help reduce the likelihood of feedback. Check out the following article to learn more:


How far does the Bluetooth connection reach?

The range of Bluetooth connection of a Job Rocker Max is up to 100 feet - as long as the transmitting audio source is not moving around and there are no obstructions between the audio source and the Job Rocker Max. The transmitting audio device (i.e. phone or tablet) should not be emitting a signal from a pocket, or be covered in any way in order to achieve the best results. The range can also be affected by the Bluetooth chipset in the audio source as well.


Do the A/C outlets work if the Job Rocker is running on battery power?

No. If you are not receiving power from the A/C outlets located on the rear of the Job Rocker Max, ensure that the Job Rocker Max is connected to a power source. If the Job Rocker Max is plugged in and you are still not receiving power from the A/C outlets, you may potential have a blown fuse.

The sound is coming out distorted. What is happening and how can I fix it?

If the sound from your Job Rocker Max is coming out distorted, try lowering the volume control of your sound source - such as your iPod or iPhone. Also, try reducing the overall volume of the Job Rocker Max.

If you continue to experience sound issues after following the suggested steps above, you may want to contract ION Tech Support.


I am getting poor AM reception. What can I do?

If you have a Bluetooth device connected to the Job Rocker Max, while you are listening to the AM radio, disconnect the Bluetooth device and the AM frequencies will likely clear up.

To continue to adjust AM reception, move the entire Job Rocker Max. Sometimes, there is a slight operating noise around the 540 kHz AM frequency, but other than that, re-positioning the unit should provide a better AM reception.


Can the Job Rocker Max be used in a foreign country?

The Job Rocker Max can only be used in the country for which it was designed to be used. The Job Rocker Max cannot be adjusted for use in a country with a different electrical current than it was manufactured to be used with.
