ELECTRICAL SAFETY

This product is designed for operation with power supply via the USB port. Any other use
maybe endangers and leads to a loss of all claims under warranty for this product.

SAFETY NOTE CONCERNING DIRECT SUNLIGHT

Make sure that the device is not exposed to excessive humidity and extreme temperatures,
such as a car dashboard, a windowsill or directly behind a glass pane, which is directly
exposed to the sun or very strong UV light. Otherwise, the device or the vehicle might be
damaged.

DAMAGES THAT NECESSITATE REPAIRS

Disconnect the product from the device connected in the following cases.



A liquid or object has penetrated into the product.



The product has fallen on the oor or has been damaged.



There are visible signs of overheating.



The product does not work awlessly even though handled appropriately.

AVOID USING THE PRODUCT DIRECTLY AFTER STRONG FLUCTUATIONS IN
TEMPERATURE.

If the unit is exposed to strong temperature and humidity uctuations, this may lead to

condensation of water inside the unit. In the purpose of avoiding damage to the unit,
please wait until the humidity has evaporated before using the unit.

Note: When you bring the product from a cold to a warm environment, and vice versa,
allow the product to acclimate to the temperature before you power it on.

Select the recommended item and click “Next” button.

12

Click “Continue anyway”.

13

Click “Finish” to complete it.

14

Enter “Device Manager” to reconfirm if the USB driver is installed successfully

and the assigned COM Port (under connection). Set this port in your navigation

software. Do not use another program that accesses this port at the same time.

15

TROUBLE SHOOTING

The GPS signal will become not good enough under the environment of tall buildings

and trees. Even though the WGM-302 can receive reected GPS signal, the data

might be less accurate.
Some car window lm comprising too many metals would affect a reception of signal.
The unstable atmospheric condition will effect a worse accuracy; however, if the

location on map is always shifted no matter how signal is, please reconrm if the

datum system on the map you used is the standard WGS-84 or not.
The WGM-302 utilizes initial data, such as last stored position, date, time and

almanac data, to achieve maximum acquisition performance. If significant

inaccuracy exists in the initial data, or the almanac data is obsolete, it may take

more time to get acquisition, e.g. your current location is 500km away from the latest

location you used it, or the device isn’t used for three months.
Avoid placing 2 GPS devices too close during positioning.
Before connecting the WGM-302 to the computer, please make sure the USB driver

has been installed and the right COM Port has been selected. (USB interface only)
If the WGM-302 is not working for navigation under correct connection and data

output, please reconrm the format of NMEA 0183 for your navigation software, and

set it via the WGM-302 Tool.

WARRANTY

The WGM-302 is warranted to be free from defects in materials and functions for one
year from the date of purchase. Within this period, Wintec will, at its sole option, repair
or replace any components that fail in normal use. Such repairs or replacement will be
made at no charge to the customer for parts or labor, provided that the customer shall be
responsible for any transportation cost.

注意事項



全球衛星定位系統(

Global Positioning System; GPS

) 由美國政府所提供，並負責
該系統的正常運作及定位精度的控制，基於美國本身的政策考量或國防安全，美國
有權在不預先通知或公告的狀況下，降低整個系統的功能或定位精確度(如在戰爭
時或刻意封鎖某一區域時)，美國政單位所做的任何變動都可能影響

設備的

精 準 度 及性 能。



安裝

WGM-302

時需自行考慮安裝位置安全性。如汽車安全氣囊、容易因事故衝
擊到駕駛或乘客的位置等，均不適合放置。此外，為了您的行車安全，我們強烈建
議您不要於駕駛中同時操作本裝置。



導航期間，若您位於建築物內(如地下停車場)、隧道或周邊有高大地形地物阻擋
時，

GPS

衛星訊號的接收可能因受影響而導致暫時斷訊(失去定位)，此時並非裝置

故 障，只 要

WGM-302

再次定位時，導航即會恢復正常。



請勿任意更換或改裝機械結構及零件，以免失去保固權益。



請勿在飛機飛行中或炸礦遙控等敏感度較高地區使用。



避免放置於高溫及高濕度地方太久。

疑難排解

13



在高樓林立或樹木遮蔽天空的環境，可能會導致收訊不良的情況。雖然

WGM-302

14

可接收很微弱或甚至是反射的

GPS

衛星信號，但在此情況下，定位的精確度也

勢必會受 到 一定 的 影 響。



不穩定的大氣層變化亦會影響定位準確度。然而若您發現無論信號好壞，在地

15

圖上的位置卻總是偏移，請確認您所使用的地圖，其座標系統是否為6 點標準的

WGS-

84

座 標 系 統。



WGM-302

利用內部儲存的初始資料，包含前次儲存的最後有效位置、時間與星曆
資料，推算出目前天空所在的衛星分佈並加以追蹤鎖定，以達到最佳的定位效能。
當內部儲存的初始化資料不正確，或星曆資料已過期時，則會導致較久的定位時
間。若您持續超過三個月以上未使用本機，或距離您上次使用時的關機位置超過

800

公 里，

WGM-302

會採用冷開機模式來縮短定位時間。



定位時請勿讓 2 套

GPS

裝置太靠近，以免影響收訊。
