Read and follow all of Whelen’s written instructions when installing or using this device. Emergency vehicles are often operated under high speed stressful conditions which must be accounted for when installing all emergency warning devices. Controls should be placed within convenient reach of the operator so that they can operate the system without taking their eyes off the roadway. Emergency warning devices can require high electrical voltages and/or currents. Properly protect and use caution around live electrical connections.Grounding or shorting of electrical connections can cause high current arcing, which can cause personal injury and/or vehicle damage, including fire. Many electronic devices used in emergency vehicles can create or be affected by electromagnetic interference. Therefore, after installation of any electronic device it is necessary to test all electronic equipment simultaneously to insure that they operate free of interference from other components within the vehicle. Never power emergency warning equipment from the same circuit or share the same grounding circuit with radio communication equipment. All devices should be mounted in accordance with the manufacturer’s instructions and securely fastened to vehicle elements of sufficient strength to withstand the forces applied to the device. Driver and/or passenger air bags (SRS) will affect the way equipment should be mounted. This device should be mounted by permanent installation and within the zones specified by the vehicle manufacturer, if any. Any device mounted in the deployment area of an air bag will damage or reduce the effectiveness of the air bag and may damage or dislodge the device. Installer must be sure that this device, its mounting hardware and electrical supply wiring does not interfere with the air bag or the SRS wiring or sensors. Mounting the unit inside the vehicle by a method other than permanent installation is not recommended as unit may become dislodged during swerving; sudden braking or collision. Failure to follow instructions can result in personal injury. Whelen assumes no liability for any loss resulting from the use of this warning device. PROPER INSTALLATION COMBINED WITH OPERATOR TRAINING IN THE PROPER USE OF EMERGENCY WARNING DEVICES IS ESSENTIAL TO INSURE THE SAFETY OF EMERGENCY PERSONNEL AND THE PUBLIC.Warnings to UsersWhelen’s emergency vehicle warning devices are intended to alert other operators and pedestrians to the presence and operation of emergency vehicles and personnel. However, the use of this or any other Whelen emergency warning device does not guarantee that you will have the right-of-way or that other drivers and pedestrians will properly heed an emergency warning signal. Never assume you have the right-of-way. It is your responsibility to proceed safely before entering an intersection, driving against traffic, responding at a high rate of speed, or walking on or around traffic lanes. Emergency vehicle warning devices should be tested on a daily basis to ensure that they operate properly. When in actual use, the operator must ensure that both visual and audible warnings are not blocked by vehicle components (i.e.: open trunks or compartment doors), people, vehicles, or other obstructions. It is the user’s responsibility to understand and obey all laws regarding emergency warning devices. The user should be familiar with all applicable laws and regulations prior to the use of any emergency vehicle warning device. Whelen’s audible warning devices are designed to project sound in a forward direction away from the vehicle occupants. However, because sustained periodic exposure to loud sounds can cause hearing loss, all audible warning devices should be installed and operated in accordance with the standards established by the National Fire Protection Association.Safety FirstThis document provides all the necessary information to allow your Whelen product to be properly and safely installed. Before beginning the installation and/or operation of your new product, the installation technician and operator must read this manual completely. Important information is contained herein that could prevent serious injury or damage.IMPORTANT! READ THESE WARNINGS BEFORE CONTINUING!The Howler™ Supplemental Siren was designed for use in high-risk areas such as an intersection. It is not intended to be, nor should be operated as a replacement or alternative to the vehicle’s primary siren.The low-frequency tones of the Howler demonstrate significantly different audio characteristics as compared to those of a traditional higher-frequency siren. While the low-frequency tones are better able to penetrate other vehicles, thus alerting drivers to the presence of the responding emergency vehicle, these tones may also penetrate into the responding vehicle itself. This could potentially expose the operator to increased noise levels.To help eliminate overexposure, the Howler siren has been designed with a built-in timing circuit. The Occupational Safety & Health Administration (OSHA) () provides information necessary to determine safe exposure times in Noise and Hearing Conservation, Section 1910.95 (Occupational Noise Exposure). Until you have determined the safe exposure times for your specific application, this siren should be configured for the minimum operating time and operators should be required to use an approved hearing protection device. FAILURE TO FOLLOW THIS RECOMMENDATION COULD CAUSE HEARING LOSS!IMPORTANT: It is the responsibility of the installation technician to make sure that the installation and operation of this product will not interfere with or compromise the operation or efficiency of any vehicle equipment!Note: The Howler siren speaker may only be installed on the driver-side of a2020 Dodge Charger.1.Remove and discard the existing brackets and hardware (if present) fromyour Howler Siren Speaker (Fig. 1).2.With the bracket and Howler speaker properly oriented (with screened ventopenings facing downwards), route the speaker wires through the wirepassage hole in the bracket and secure the speaker onto the bracket usingthe hardware provided (Fig. 2).3.Following the factory recommended procedure, remove the front bumperfascia.4.Locate and remove the two M8 bumper bolts from the far left end of thebumper.

3、某些无线客户端在距离AP太近的情况下可能会出现无线信号很不稳定的现象.
4、传输设备链路不稳定或者带宽不够
✓ 问题解决: 1、针对第一个原因,需要调整AP的布网环境和信道
设置,避免相邻AP的信道一样. 2、针对第二个原因,移动无线客户端到AP天线的覆
盖范围内,寻找信号强度最好传输速率最稳定的位置摆放AP. 3、针对第三个原因,移动无线客户端远离AP,一般情况下需要将AP和无线客户端网卡的距离相距大于 3米以上. 4、直接通过热点交换机来检查是否有线传输链路是否出现故障
用户有时因误操作或某种需要，指定了无线网卡的IP地址，而运营WLAN一般使用的是自动获得 IP地址，因此用户会无法登陆网络。 3、AC设备问题
在左边的菜单栏中，分别有“Channel”、“SSIDs”和“Filters”三个菜单栏，“Channel”中列出了周围所有AP工作的信道；“SSIDs”中列出了周围AP的SSID名称。根据SSID名称和MAC地址查找目标AP。
测试软件的使用
根据MAC地址查到目标AP后，从左边菜单栏中选中该目标AP （MAC地址标记的绿色图标），选中后在右边会实时显示出当前无线终端与该AP直接无线链路的实时信号强度。该值以负值表示，其绝对值越小越好（绿色线条越高越好）。良好的无线覆盖网络，其覆盖范围内的各个点的信号强度不应低于-80dBm。否则其链路将会不稳定，产生丢包等情况。
